suspend/resume"
This reverts commit 8f2f748b0656257153bcf0941df8d6060acc5ca6.
It causes some odd regression that we have not figured out, and it's too
late in the -rc series to try to figure it out now.
As reported by Konstantin Khlebnikov, it causes consistent hangs on his
laptop (Thinkpad x220: 2x cores + HT). They can be avoided by adding
calls to "rebuild_sched_domains();" in cpuset_cpu_[in]active() for the
CPU_{ONLINE/DOWN_FAILED/DOWN_PREPARE}_FROZEN cases, but it's not at all
clear why, and it makes no sense.
Konstantin's config doesn't even have CONFIG_CPUSETS enabled, just to
make things even more interesting. So it's not the cpusets, it's just
the scheduling domains.
So until this is understood, revert.

When a CPU is taken out of reset, either cold booted or hotplugged in,
some of its PMU registers can contain UNKNOWN values.
This patch adds a hotplug notifier to ARM core perf code so that upon
CPU restart the PMU unit is reset and becomes ready to use again.

xscale2 PMUs indicate overflow not via the PMU control register, but by
a separate overflow FLAG register instead.
This patch fixes the xscale2 PMU code to use this register to detect
to overflow and ensures that we clear any pending overflow when
disabling a counter.

The PMU IRQ handlers in perf assume that if a counter has overflowed
then perf must be responsible. In the paranoid world of crazy hardware,
this could be false, so check that we do have a valid event before
attempting to dereference NULL in the interrupt path.

When disabling a counter on an ARMv7 PMU, we should also clear the
overflow flag in case an overflow occurred whilst stopping the counter.
This prevents a spurious overflow being picked up later and leading to
either false accounting or a NULL dereference.

On ARM, the PMU does not stop counting after an overflow and therefore
IRQ latency affects the new counter value read by the kernel. This is
significant for non-sampling runs where it is possible for the new value
to overtake the previous one, causing the delta to be out by up to
max_period events.
Commit a737823d ("ARM: 6835/1: perf: ensure overflows aren't missed due
to IRQ latency") attempted to fix this problem by allowing interrupt
handlers to pass an overflow flag to the event update function, causing
the overflow calculation to assume that the counter passed through zero
when going from prev to new. Unfortunately, this doesn't work when
overflow occurs on the perf_task_tick path because we have the flag
cleared and end up computing a large negative delta.
This patch removes the overflow flag from armpmu_event_update and
instead limits the sample_period to half of the max_period for
non-sampling profiling runs.

Pull networking fixes from David Miller:
1) TCP can chop up SACK'd SKBs below below the unacked send sequence and
that breaks lots of stuff. Fix from Neal Cardwell.
2) There is code in ipv6 to properly join and leave the all-routers
multicast code when the forwarding setting is changed, but once
forwarding is turned on, we don't do the join for newly registered
devices. Fix from Li Wei.
3) Netfilter's NAT module autoload in ctnetlink drops a spinlock around
a sleeping call, problem is this code path doesn't actually hold that
lock. Fix from Pablo Neira Ayuso.
4) TG3 uses the wrong interfaces to hook into the new byte queue limit
support. It uses the device level interfaces, which is fine for
single queue devices, but on more recent chips this driver supports
multiqueue so we have to use the multiqueue BQL APIs. Fix from Tom
Herbert.
5) r8169 resume fix from Francois Romieu.

It turns out that test-compiling this file on x86-64 doesn't really
help, because much of it is x86-32-specific. And so I hadn't noticed
the slightly over-eager removal of the 'r' from 'addr' variable despite
thinking I had tested it.

Several users of "find_vma_prev()" were not in fact interested in the
previous vma if there was no primary vma to be found either. And in
those cases, we're much better off just using the regular "find_vma()",
and then "prev" can be looked up by just checking vma->vm_prev.
The find_vma_prev() semantics are fairly subtle (see Mikulas' recent
commit 83cd904d271b: "mm: fix find_vma_prev"), and the whole "return
prev by reference" means that it generates worse code too.
Thus this "let's avoid using this inconvenient and clearly too subtle
interface when we don't really have to" patch.

Pull CIFS fixes from Steve French

Commit 6bd4837de96e ("mm: simplify find_vma_prev()") broke memory
management on PA-RISC.
After application of the patch, programs that allocate big arrays on the
stack crash with segfault, for example, this will crash if compiled
without optimization:
int main()
{
char array[200000];
array[199999] = 0;
return 0;
}
The reason is that PA-RISC has up-growing stack and the stack is usually
the last memory area. In the above example, a page fault happens above
the stack.
Previously, if we passed too high address to find_vma_prev, it returned
NULL and stored the last VMA in *pprev. After "simplify find_vma_prev"
change, it stores NULL in *pprev. Consequently, the stack area is not
found and it is not expanded, as it used to be before the change.
This patch restores the old behavior and makes it return the last VMA in
*pprev if the requested address is higher than address of any other VMA.

Xommit ac5637611(genirq: Unmask oneshot irqs when thread was not woken)
fails to unmask when a !IRQ_ONESHOT threaded handler is handled by
handle_level_irq.
This happens because thread_mask is or'ed unconditionally in
irq_wake_thread(), but for !IRQ_ONESHOT interrupts never cleared. So
the check for !desc->thread_active fails and keeps the interrupt
disabled.
Keep the thread_mask zero for !IRQ_ONESHOT interrupts.
Document the thread_mask magic while at it.

When net.bridge.bridge-nf-filter-vlan-tagged is 0 (default), vlan packets
arriving should not be sent to ip(6)tables by bridge netfilter.
However, it turns out that we currently always send VLAN packets to
netfilter, if ..
a), CONFIG_VLAN_8021Q is enabled ; or
b), CONFIG_VLAN_8021Q is not set but rx vlan offload is enabled
on the bridge port.
This is because bridge netfilter treats skb with
skb->protocol == ETH_P_IP{V6} as "non-vlan packet".
With rx vlan offload on or CONFIG_VLAN_8021Q=y, the vlan header has
already been removed here, and we cannot rely on skb->protocol alone.
Fix this by only using skb->protocol if the skb has no vlan tag,
or if a vlan tag is present and filter-vlan-tagged bridge netfilter
sysctl is enabled.
We cannot remove the skb->protocol == htons(ETH_P_8021Q) test
because the vlan tag is still around in the CONFIG_VLAN_8021Q=n &&
"ethtool -K $itf rxvlan off" case.
reproducer:
iptables -t raw -I PREROUTING -i br0
iptables -t raw -I PREROUTING -i br0.1
Then send packets to an ip address configured on br0.1 interface.
Even with net.bridge.bridge-nf-filter-vlan-tagged=0, the 1st rule
will match instead of the 2nd one.
With this patch applied, the 2nd rule will match instead.
In the non-local address case, netfilter won't be consulted after
this patch unless the sysctl is switched on.

With runtime PM, if the ethernet cable is disconnected, the device is
transitioned to D3 state to conserve energy. If the system is shutdown
in this state, any register accesses in rtl_shutdown are dropped on
the floor. As the device was programmed by .runtime_suspend() to wake
on link changes, it is thus brought back up as soon as the link recovers.
Resuming every suspended device through the driver core would slow things
down and it is not clear how many devices really need it now.

This commit fixes tcp_shift_skb_data() so that it does not shift
SACKed data below snd_una.
This fixes an issue whose symptoms exactly match reports showing
tp->sacked_out going negative since 3.3.0-rc4 (see "WARNING: at
net/ipv4/tcp_input.c:3418" thread on netdev).
Since 2008 (832d11c5cd076abc0aa1eaf7be96c81d1a59ce41)
tcp_shift_skb_data() had been shifting SACKed ranges that were below
snd_una. It checked that the *end* of the skb it was about to shift
from was above snd_una, but did not check that the end of the actual
shifted range was above snd_una; this commit adds that check.
Shifting SACKed ranges below snd_una is problematic because for such
ranges tcp_sacktag_one() short-circuits: it does not declare anything
as SACKed and does not increase sacked_out.
Before the fixes in commits cc9a672ee522d4805495b98680f4a3db5d0a0af9
and daef52bab1fd26e24e8e9578f8fb33ba1d0cb412, shifting SACKed ranges
below snd_una happened to work because tcp_shifted_skb() was always
(incorrectly) passing in to tcp_sacktag_one() an skb whose end_seq
tcp_shift_skb_data() had already guaranteed was beyond snd_una. Hence
tcp_sacktag_one() never short-circuited and always increased
tp->sacked_out in this case.
After those two fixes, my testing has verified that shifting SACKed
ranges below snd_una could cause tp->sacked_out to go negative with
the following sequence of events:
(1) tcp_shift_skb_data() sees an skb whose end_seq is beyond snd_una,
then shifts a prefix of that skb that is below snd_una
(2) tcp_shifted_skb() increments the packet count of the
already-SACKed prev sk_buff
(3) tcp_sacktag_one() sees the end of the new SACKed range is below
snd_una, so it short-circuits and doesn't increase tp->sacked_out
(5) tcp_clean_rtx_queue() sees the SACKed skb has been ACKed,
decrements tp->sacked_out by this "inflated" pcount that was
missing a matching increase in tp->sacked_out, and hence
tp->sacked_out underflows to a u32 like 0xFFFFFFFF, which casted
to s32 is negative.
(6) this leads to the warnings seen in the recent "WARNING: at
net/ipv4/tcp_input.c:3418" thread on the netdev list; e.g.:
tcp_input.c:3418 WARN_ON((int)tp->sacked_out < 0);
More generally, I think this bug can be tickled in some cases where
two or more ACKs from the receiver are lost and then a DSACK arrives
that is immediately above an existing SACKed skb in the write queue.
This fix changes tcp_shift_skb_data() to abort this sequence at step
(1) in the scenario above by noticing that the bytes are below snd_una
and not shifting them.

kasprintf() (and potentially other functions that I didn't run across so
far) want to evaluate argument lists twice. Caring to do so for the
primary list is obviously their job, but they can't reasonably be
expected to check the format string for instances of %pV, which however
need special handling too: On architectures like x86-64 (as opposed to
e.g. ix86), using the same argument list twice doesn't produce the
expected results, as an internally managed cursor gets updated during
the first run.
Fix the problem by always acting on a copy of the original list when
handling %pV.

define dummy clock in pxa25x/pxa27x instead.
This regression was introduced by the commit "ARM: pxa: add dummy
clock for sa1100-rtc", id a55b5adaf403c4d032e0871ad4ee3367782f4db6.

Dave Jones reports a few Fedora users hitting the BUG_ON(mm->nr_ptes...)
in exit_mmap() recently.
Quoting Hugh's discovery and explanation of the SMP race condition:
"mm->nr_ptes had unusual locking: down_read mmap_sem plus
page_table_lock when incrementing, down_write mmap_sem (or mm_users
0) when decrementing; whereas THP is careful to increment and
decrement it under page_table_lock.
Now most of those paths in THP also hold mmap_sem for read or write
(with appropriate checks on mm_users), but two do not: when
split_huge_page() is called by hwpoison_user_mappings(), and when
called by add_to_swap().
It's conceivable that the latter case is responsible for the
exit_mmap() BUG_ON mm->nr_ptes that has been reported on Fedora."
The simplest way to fix it without having to alter the locking is to make
split_huge_page() a noop in nr_ptes terms, so by counting the preallocated
pagetables that exists for every mapped hugepage. It was an arbitrary
choice not to count them and either way is not wrong or right, because
they are not used but they're still allocated.

When moving tasks from old memcg (with move_charge_at_immigrate on new
memcg), followed by removal of old memcg, hit General Protection Fault in
mem_cgroup_lru_del_list() (called from release_pages called from
free_pages_and_swap_cache from tlb_flush_mmu from tlb_finish_mmu from
exit_mmap from mmput from exit_mm from do_exit).
Somewhat reproducible, takes a few hours: the old struct mem_cgroup has
been freed and poisoned by SLAB_DEBUG, but mem_cgroup_lru_del_list() is
still trying to update its stats, and take page off lru before freeing.
A task, or a charge, or a page on lru: each secures a memcg against
removal. In this case, the last task has been moved out of the old memcg,
and it is exiting: anonymous pages are uncharged one by one from the
memcg, as they are zapped from its pagetables, so the charge gets down to
0; but the pages themselves are queued in an mmu_gather for freeing.
Most of those pages will be on lru (and force_empty is careful to
lru_add_drain_all, to add pages from pagevec to lru first), but not
necessarily all: perhaps some have been isolated for page reclaim, perhaps
some isolated for other reasons. So, force_empty may find no task, no
charge and no page on lru, and let the removal proceed.
There would still be no problem if these pages were immediately freed; but
typically (and the put_page_testzero protocol demands it) they have to be
added back to lru before they are found freeable, then removed from lru
and freed. We don't see the issue when adding, because the
mem_cgroup_iter() loops keep their own reference to the memcg being
scanned; but when it comes to mem_cgroup_lru_del_list().
I believe this was not an issue in v3.2: there, PageCgroupAcctLRU and
PageCgroupUsed flags were used (like a trick with mirrors) to deflect view
of pc->mem_cgroup to the stable root_mem_cgroup when neither set.
38c5d72f3ebe ("memcg: simplify LRU handling by new rule") mercifully
removed those convolutions, but left this General Protection Fault.
But it's surprisingly easy to restore the old behaviour: just check
PageCgroupUsed in mem_cgroup_lru_add_list() (which decides on which lruvec
to add), and reset pc to root_mem_cgroup if page is uncharged. A risky
change? just going back to how it worked before; testing, and an audit of
uses of pc->mem_cgroup, show no problem.
And there's a nice bonus: with mem_cgroup_lru_add_list() itself making
sure that an uncharged page goes to root lru, mem_cgroup_reset_owner() no
longer has any purpose, and we can safely revert 4e5f01c2b9b9 ("memcg:
clear pc->mem_cgroup if necessary").
Calling update_page_reclaim_stat() after add_page_to_lru_list() in swap.c
is not strictly necessary: the lru_lock there, with RCU before memcg
structures are freed, makes mem_cgroup_get_reclaim_stat_from_page safe
without that; but it seems cleaner to rely on one dependency less.

debugobjects is now printing a warning when a fixup for a NOTAVAILABLE
object is run. This causes the selftest to fail like:
ODEBUG: selftest warnings failed 4 != 5
We could just increase the number of warnings that the selftest is
expecting to see because that is actually what has changed. But, it turns
out that fixup_activate() was written with inverted logic and thus a fixup
for a static object returned 1 indicating the object had been fixed, and 0
otherwise. Fix the logic to be correct and update the counts to reflect
that nothing needed fixing for a static object.

We have forgotten the rules of lock nesting: the irq-safe ones must be
taken inside the non-irq-safe ones, otherwise we are open to deadlock:
CPU0 CPU1
---- ----
lock(&(&pc->lock)->rlock);
local_irq_disable();
lock(&(&zone->lru_lock)->rlock);
lock(&(&pc->lock)->rlock);
<Interrupt>
lock(&(&zone->lru_lock)->rlock);
To check a different locking issue, I happened to add a spin_lock to
memcg's bit_spin_lock in lock_page_cgroup(), and lockdep very quickly
complained about __mem_cgroup_commit_charge_lrucare() (on CPU1 above).
So delete __mem_cgroup_commit_charge_lrucare(), passing a bool lrucare to
__mem_cgroup_commit_charge() instead, taking zone->lru_lock under
lock_page_cgroup() in the lrucare case.
The original was using spin_lock_irqsave, but we'd be in more trouble if
it were ever called at interrupt time: unconditional _irq is enough. And
ClearPageLRU before del from lru, SetPageLRU before add to lru: no strong
reason, but that is the ordering used consistently elsewhere.

check_hung_uninterruptible_tasks()->rcu_lock_break() introduced by
"softlockup: check all tasks in hung_task" commit ce9dbe24 looks
absolutely wrong.
- rcu_lock_break() does put_task_struct(). If the task has exited
it is not safe to even read its ->state, nothing protects this
task_struct.
- The TASK_DEAD checks are wrong too. Contrary to the comment, we
can't use it to check if the task was unhashed. It can be unhashed
without TASK_DEAD, or it can be valid with TASK_DEAD.
For example, an autoreaping task can do release_task(current)
long before it sets TASK_DEAD in do_exit().
Or, a zombie task can have ->state == TASK_DEAD but release_task()
was not called, and in this case we must not break the loop.
Change this code to check pid_alive() instead, and do this before we drop
the reference to the task_struct.
Note: while_each_thread() under rcu_read_lock() is not really safe, it can
livelock. This will be fixed later, but fortunately in this case the
"max_count" logic saves us anyway.

Make vfork() killable.
Change do_fork(CLONE_VFORK) to do wait_for_completion_killable(). If it
fails we do not return to the user-mode and never touch the memory shared
with our child.
However, in this case we should clear child->vfork_done before return, we
use task_lock() in do_fork()->wait_for_vfork_done() and
complete_vfork_done() to serialize with each other.
Note: now that we use task_lock() we don't really need completion, we
could turn task->vfork_done into "task_struct *wake_up_me" but this needs
some complications.
NOTE: this and the next patches do not affect in-kernel users of
CLONE_VFORK, kernel threads run with all signals ignored including
SIGKILL/SIGSTOP.
However this is obviously the user-visible change. Not only a fatal
signal can kill the vforking parent, a sub-thread can do execve or
exit_group() and kill the thread sleeping in vfork().

The problem lies with the allocation batching code. It will
opportunistically allocate kiocbs, and then trim back the list of iocbs
when there is not enough room in the completion ring to hold all of the
events.
In the case above, what happens is that the pruning back of events ends
up freeing up the last active request and the context is marked as dead,
so it is thus responsible for waking up waiters. Unfortunately, the
code does not check for this condition, so we end up with a hung task.

Since commit 04c6862c055f ("kmsg_dump: add kmsg_dump() calls to the
reboot, halt, poweroff and emergency_restart paths"), kmsg_dump() gets
run on normal paths including poweroff and reboot.
This is less than ideal given pstore implementations that can only
represent single backtraces, since a reboot may overwrite a stored oops
before it's been picked up by userspace. In addition, some pstore
backends may have low performance and provide a significant delay in
reboot as a result.
This patch adds a printk.always_kmsg_dump kernel parameter (which can also
be changed from userspace). Without it, the code will only be run on
failure paths rather than on normal paths. The option can be enabled in
environments where there's a desire to attempt to audit whether or not a
reboot was cleanly requested or not.

Production GMA3600/3650 hardware turns out to be subtly different to the
development platforms. This combined with a minor driver bug is causing
the kernel to hang on these platforms.
This patch does the following
- turn down a couple of messages that were meant to be debug and are
causing much confusion
- ensure the hotplug interrupt is disabled on Cedartrail systems.
- fix a bug where gtt roll mode called psbfb_sync, which tries to sync
the 2D engine. On other devices it is harmless as the 2D engine is
present but not in use when in gtt roll mode, on Cedartrail it causes
a hang
Without these changes 3.3-rc hangs on boot on Cedartrail based systems.

Pull networking fixes from David Miller:
1) TCP SACK processing can calculate an incorrect reordering value in
some cases, fix from Neal Cardwell.
2) tcp_mark_head_lost() can split SKBs in situations where it should
not, violating send queue invariants expected by other pieces of
code and thus resulting (eventually) in corrupted retransmit state
counters. Also from Neal Cardwell.
3) qla3xxx erroneously calls spin_lock_irqrestore() with constant
hw_flags of zero. Fix from Santosh Nayak.
4) Fix NULL deref in rt2x00, from Gabor Juhos.
5) pch_gbe passes address of wrong typed object to pch_gbe_validate_option
thus corrupting part of the value. From Dan Carpenter.
6) We must check the return value of nlmsg_parse() before trying to use
the results. From Eric Dumazet.
7) Bridging code fails to check return value of ipv6_dev_get_saddr()
thus potentially leaving uninitialized garbage in the outgoing ipv6
header. From Ulrich Weber.
8) Due to rounding and a reversed operation on jiffies, bridge message
ages can go backwards instead of forwards, thus breaking STP. Fixes
from Joakim Tjernlund.
9) r8169 modifies Config* registers without properly holding the
Config9346 lock, resulting in corrupted IP fragments on some chips.
Fix from Francois Romieu.
10) NET_PACKET_ENGINE default wan't set properly during the network
driver mega-move. Fix from Stephen Hemminger.
11) vmxnet3 uses TCP header size where it actually should use the UDP
header size, fix from Shreyas Bhatewara.
12) Netfilter bridge module autoload is busted in the compat case, fix
from Florian Westphal.
13) Wireless Key removal was not setting multicast bits correctly thus
accidently killing the unicast key 0 and thus all traffic stops.
Fix from Johannes Berg.
14) Fix endless retries of A-MPDU transmissions in brcm80211 driver.

All other callers already hold either ->mmap_sem (exclusive) or
->page_table_lock. And we need it because some page table flushing
instanced do work explicitly with ge tables.
See e.g. arch/powerpc/mm/tlb_hash32.c, flush_tlb_range() and
flush_range() in there. The same goes for uml, with a lot more
extensive playing with page tables.
Almost all callers are actually fine - flush_tlb_range() may have no
need to bother playing with page tables, but it can do so safely; again,
this caller is the sole exception - everything else either has exclusive
->mmap_sem on the mm in question, or mm->page_table_lock is held.

Allow array field values out of range as per HID 1.11 specification,
section 6.2.25:
Rather than returning a single bit for each button in the group, an
array returns an index in each field that corresponds to the pressed
button (like keyboard scan codes). An out-of range value in and array
field is considered no controls asserted.
Apparently, "and" above is a typo and should be "an".

It's only used inside fs/dcache.c, and we're going to play games with it
for the word-at-a-time patches. This time we really don't even want to
export it, because it really is an internal function to fs/dcache.c, and
has been since it was introduced.
Having it in that extremely hot header file (it's included in pretty
much everything, thanks to <linux/fs.h>) is a disaster for testing
different versions, and is utterly pointless.
We really should have some kind of header file diet thing, where we
figure out which parts of header files are really better off private and
only result in more expensive compiles.

Even if cards supports 1.8V I/O voltage those should anyway be
initialized at 3.3V I/O according to (e)MMC, SD and SDIO specs.
Some eMMC and embedded SDIO devices are able to be initialized
at 1.8V as well, but it is better to be safe.
Do note that initialization in this context means that the card
has been completely powered off, otherwise the card will remain
at the last I/O voltage level that were negotitiated.
Due to the above being taken care of the suspend/resume issues
for UHS-I SD-cards has been fixed.

On i.MX53 we have to write a special SDHCI_CMD_ABORTCMD to the
SDHCI_TRANSFER_MODE register during a MMC_STOP_TRANSMISSION
command. This works for SD cards. However, with MMC cards
the MMC_SET_BLOCK_COUNT command is used instead, but this
needs the same handling. Fix MMC cards by testing for the
MMC_SET_BLOCK_COUNT command aswell. Tested on a custom i.MX53
board with a Transcend MMC+ card and eMMC.
The kernel started used MMC_SET_BLOCK_COUNT in 3.0, so this
is a regression for these boards introduced in 3.0; it should
go to 3.0/3.1/3.2-stable.

A recent commit "mmc: core: Use delayed work in clock gating framework"
(597dd9d79cfbbb1) introduced a default 200ms delay before clock gating
actually takes place. This means that every time an MMC interface
becomes idle it first stays on for 200ms before gating its clock. This
leads to increased power consumption and is therefore a clear regression.
This patch restores the original behaviour by setting the default delay
to 0. Users prioritising throughput over power efficiency can still
modify the delay via sysfs.

In tcp_mark_head_lost() we should not attempt to fragment a SACKed skb
to mark the first portion as lost. This is for two primary reasons:
(1) tcp_shifted_skb() coalesces adjacent regions of SACKed skbs. When
doing this, it preserves the sum of their packet counts in order to
reflect the real-world dynamics on the wire. But given that skbs can
have remainders that do not align to MSS boundaries, this packet count
preservation means that for SACKed skbs there is not necessarily a
direct linear relationship between tcp_skb_pcount(skb) and
skb->len. Thus tcp_mark_head_lost()'s previous attempts to fragment
off and mark as lost a prefix of length (packets - oldcnt)*mss from
SACKed skbs were leading to occasional failures of the WARN_ON(len >
skb->len) in tcp_fragment() (which used to be a BUG_ON(); see the
recent "crash in tcp_fragment" thread on netdev).
(2) there is no real point in fragmenting off part of a SACKed skb and
calling tcp_skb_mark_lost() on it, since tcp_skb_mark_lost() is a NOP
for SACKed skbs.

The code in link_path_walk() that finds out the length and the hash of
the next path component is some of the hottest code in the kernel. And
I have a version of it that does things at the full width of the CPU
wordsize at a time, but that means that we *really* want to split it up
into a separate helper function.
So this re-organizes the code a bit and splits the hashing part into a
helper function called "hash_name()". It returns the length of the
pathname component, while at the same time computing and writing the
hash to the appropriate location.
The code generation is slightly changed by this patch, but generally for
the better - and the added abstraction actually makes the code easier to
read too. And the new interface is well suited for replacing just the
"hash_name()" function with alternative implementations.

.. and also use it in lookup_one_len() rather than open-coding it.
There aren't any performance-critical users, so inlining it is silly.
But it wouldn't matter if it wasn't for the fact that the word-at-a-time
dentry name patches want to conditionally replace the function, and
uninlining it sets the stage for that.
So again, this is a preparatory patch that doesn't change any semantics,

The F75387 supports automatic fan control using either PWM duty cycle or
RPM speed values. Make the driver detect the latter mode, and expose the
different modes in sysfs as per pwm_enable, so that the user can switch
between them.
The interpretation of the pwm_enable attribute for the F75387 is adjusted
to be a superset of those values used for similar Fintek chips which do
not support automatic duty mode, with 2 mapping to automatic speed mode,
and moving automatic duty mode to the new value 4.
Toggling the duty mode via pwm_enable is currently denied for the F75387,
as the chip then simply reinterprets the fan configuration register values
according to the new mode, switching between RPM and PWM units, which
makes this a dangerous operation.
This patch introduces a new pwm mode into the driver. This is necessary
because the new mode (automatic pwm mode, 4) may already be enabled by the
BIOS, and the driver should not break existing functionality. This was seen
on at least one board.

It turned out that a performance counter on AMD does not
count at all when the GO or HO bit is set in the control
register and SVM is disabled in EFER.
This patch works around this issue by masking out the HO bit
in the performance counter control register when SVM is not
enabled.
The GO bit is not touched because it is only set when the
user wants to count in guest-mode only. So when SVM is
disabled the counter should not run at all and the
not-counting is the intended behaviour.

pci=use_crs to the kernel command line, no more trouble.
Ok, we can add a quirk. dmidecode output reveals that this is an MSI
MS-7253, for which we already have a quirk, but the short-sighted
author tied the quirk to a single BIOS version, making it not kick in
on Carlos's machine with BIOS V1.2. If a later BIOS update makes it
no longer necessary to look at the _CRS info it will still be
harmless, so let's stop trying to guess which versions have and don't

memblock allocator aligns @size to @align to reduce the amount
of fragmentation. Commit:
7bd0b0f0da ("memblock: Reimplement memblock allocation using reverse free area iterator")
Broke it by incorrectly relocating @size aligning to
memblock_find_in_range_node(). As the aligned size is not
propagated back to memblock_alloc_base_nid(), the actually
reserved size isn't aligned.
While this increases memory use for memblock reserved array,
this shouldn't cause any critical failure; however, it seems
that the size aligning was hiding a use-beyond-allocation bug in
sparc64 and losing the aligning causes boot failure.
The underlying problem is currently being debugged but this is a
proper fix in itself, it's already pretty late in -rc cycle for
boot failures and reverting the change for debugging isn't
difficult. Restore the size aligning moving it to
memblock_alloc_base_nid().

Commit b27b072791dc (ARM: 7265/1: restart: S3C24XX: use new restart hook)
introduced the new restart hook also for the S3C244x cpus, but it
was only defined in the S3C2440 scope, i.e. when CPU_S3C2440 was
selected. Devices using the S3C2442 like the GTA02 normally don't select
this CPU which leads to compilation errors like:
LD .tmp_vmlinux1
arch/arm/mach-s3c2440/built-in.o:(.arch.info.init+0x3c): undefined reference
to `s3c2440_restart'
make: *** [.tmp_vmlinux1] Error 1
Therefore move the s3c2440_restart function to s3c244x.c which is
common to both cpus and also fix the naming to reflect this.

virtio: balloon: leak / fill balloon across S4
|
|
commit e562966dbaf49e7804097cd991e5d3a8934fc148 added support for S4 to
the balloon driver. The freeze function did nothing to free the pages,
since reclaiming the pages from the host to immediately give them back
(if S4 was successful) seemed wasteful. Also, if S4 wasn't successful,
the guest would have to re-fill the balloon. On restore, the pages were
supposed to be marked freed and the free page counters were incremented
to reflect the balloon was totally deflated.
However, this wasn't done right. The pages that were earlier taken away
from the guest during a balloon inflation operation were just shown as
used pages after a successful restore from S4. Just a fancy way of
leaking lots of memory.
Instead of trying that, just leak the balloon on freeze and fill it on
restore/thaw paths. This works properly now. The optimisation to not
leak can be added later on after a bit of refactoring of the code.

ovl->enable/disable are meant to be synchronous so that they can handle
the configuration of fifo sizes. The current kernel doesn't configure
fifo sizes yet, and so the code doesn't need to block to function (from
omapdss driver's perspective).
However, for the users of omapdss a non-blocking ovl->disable is
confusing, because they don't know when the memory area is not used
any more.
Furthermore, when the fifo size configuration is added in the next merge
window, the change from non-blocking to blocking could cause side
effects to the users of omapdss. So by making the functions block
already will keep them behaving in the same manner.
And, while not the main purpose of this patch, this will also remove the
compile warning:

tg3_get_stats64() takes tp->lock when dealing with non-serdes bcm5700
and bcm5701 devices. However, functions that call tg3_halt() have
already acquired tp->lock. When tg3_get_stats64() is called in
tg3_halt(), deadlock will occur.
This patch fixes the problem by separating the stat gathering code into
a new tg3_get_nstats() function. tg3_get_stats64() is recoded to call
this function and take tp->lock. The code that takes tp->lock in
tg3_calc_crc_errors() has been removed. Function signatures have been
cleaned up too.

Some codecs don't supply the mute amp-capabilities although the lowest
volume gives the mute. It'd be handy if the parser provides the mute
mixers in such a case.
This patch adds an extension amp-cap bit (which is used only in the
driver) to represent the min volume = mute state. Also modified the
amp cache code to support the fake mute feature when this bit is set
but the real mute bit is unset.
In addition, conexant cx5051 parser uses this new feature to implement
the missing mute controls.

When tcp_shifted_skb() shifts bytes from the skb that is currently
pointed to by 'highest_sack' then the increment of
TCP_SKB_CB(skb)->seq implicitly advances tcp_highest_sack_seq(). This
implicit advancement, combined with the recent fix to pass the correct
SACKed range into tcp_sacktag_one(), caused tcp_sacktag_one() to think
that the newly SACKed range was before the tcp_highest_sack_seq(),
leading to a call to tcp_update_reordering() with a degree of
reordering matching the size of the newly SACKed range (typically just
1 packet, which is a NOP, but potentially larger).
This commit fixes this by simply calling tcp_sacktag_one() before the
TCP_SKB_CB(skb)->seq advancement that can advance our notion of the
highest SACKed sequence.
Correspondingly, we can simplify the code a little now that
tcp_shifted_skb() should update the lost_cnt_hint in all cases where
skb == tp->lost_skb_hint.

In the spirit of commit 29cf7a30f8a0 ("x86/PCI: use host bridge _CRS
info on ASUS M2V-MX SE"), this DMI quirk turns on "pci_use_crs" by
default on a board that needs it.
This fixes boot failures and oopses introduced in 3e3da00c01d0
("x86/pci: AMD one chain system to use pci read out res"). The quirk
is quite targetted (to a specific board and BIOS version) for two
reasons:
(1) to emphasize that this method of tackling the problem one quirk
at a time is a little insane
(2) to give BIOS vendors an opportunity to use simpler tables and
allow us to return to generic behavior (whatever that happens to
be) with a later BIOS update
In other words, I am not at all happy with having quirks like this.
But it is even worse for the kernel not to work out of the box on
these machines, so...

IOMMU fixes for Linux 3.3-rc5
All the fixes are for the OMAP IOMMU driver. The first patch is the
biggest one. It fixes the calls of the function omap_find_iovm_area() in
the omap-iommu-debug module which expects a 'struct device' parameter
since commit fabdbca instead of an omap_iommu handle. The
omap-iommu-debug code still passed the handle to the function which
caused a crash.
The second patch fixes a NULL pointer dereference in the OMAP code and
the third patch makes sure that the omap-iommu is initialized before the
omap-isp driver, which relies on the iommu. The last patch is only a
workaround until defered probing is implemented.

This makes mount take slightly longer, but at the same time, the first
write to the filesystem will be faster too. It also means that if there
is a problem in the resource index, then we can refuse to mount rather
than having to try and report that when the first write occurs.
In addition, to avoid recursive locking, we hvae to take account of
instances when the rindex glock may already be held when we are
trying to update the rbtree of resource groups.

This patch fixes a problem whereby gfs2_grow was failing and causing GFS2
to assert. The problem was that when GFS2's fallocate operation tried to
acquire an "allocation" it made sure the rindex was up to date, and if not,
it called gfs2_rindex_update. However, if the file being fallocated was
the rindex itself, it was already locked at that point. By calling
gfs2_rindex_update at an earlier point in time, we bring rindex up to date
and thereby avoid trying to lock it when the "allocation" is acquired.

While demoing ktest at ELC in 2012, it was embarrassing that the
make_min_config test failed to work because the snowball board I was
testing it against had a config that would not build. But the
make_min_config only tested the testing part and ignored build failures.
The end result was a config file that would not boot.
This time, for real.

ktest: Fix make_min_config test when build fails
|
|
The make_min_config does not take into account when the build fails,
resulting in a invalid MIN_CONFIG .config file. When the build fails,
it is ignored and the boot test is executed, using the previous built
kernel. The configs that should be tested are not tested and they may
be added or removed depending on the result of the last kernel that
succeeded to be built.
If the build fails, mark the current config as a failure and the
configs that were disabled may still be needed.

This is a revert of 6aa56062eaba67adfb247cded244fd877329588d.
This was originally introduced to workaround reads of the ringbuffer
registers returning 0 on SandyBridge causing hangs due to ringbuffer
overflow. The root cause here was reads through the GT powerwell require
the forcewake dance, something we only learnt of later. Now it appears
that reading the reported head position from the HWS is returning
garbage, leading once again to hangs.
For example, on q35 the autoreported head reports:
[ 217.975608] head now 00010000, actual 00010000
[ 436.725613] head now 00200000, actual 00200000
[ 462.956033] head now 00210000, actual 00210010
[ 485.501409] head now 00400000, actual 00400020
[ 508.064280] head now 00410000, actual 00410000
[ 530.576078] head now 00600000, actual 00600020
[ 553.273489] head now 00610000, actual 00610018
which appears reasonably sane. In contrast, if we look at snb:
[ 141.970680] head now 00e10000, actual 00008238
[ 141.974062] head now 02734000, actual 000083c8
[ 141.974425] head now 00e10000, actual 00008488
[ 141.980374] head now 032b5000, actual 000088b8
[ 141.980885] head now 03271000, actual 00008950
[ 142.040628] head now 02101000, actual 00008b40
[ 142.180173] head now 02734000, actual 00009050
[ 142.181090] head now 00000000, actual 00000ae0
[ 142.183737] head now 02734000, actual 00009050
In addition, the automatic reporting of the head position is scheduled
to be defeatured in the future. It has no more utility, remove it.

functions conditional
The problem in
commit fea80311a939a746533a6d7e7c3183729d6a3faf
Author: Randy Dunlap <rdunlap@xenotime.net>
Date: Sun Jul 24 11:39:14 2011 -0700
iomap: make IOPORT/PCI mapping functions conditional
is that if your architecture supplies pci_iomap/pci_iounmap, it expects
always to supply them. Adding empty body defitions in the !CONFIG_PCI
case, which is what this patch does, breaks the parisc compile because
the functions become doubly defined. It took us a while to spot this,
because we don't actually build !CONFIG_PCI very often (only if someone
is brave enough to test the snake/asp machines).
Since the note in the commit log says this is to fix a
CONFIG_GENERIC_IOMAP issue (which it does because CONFIG_GENERIC_IOMAP
supplies pci_iounmap only if CONFIG_PCI is set), there should actually
have been a condition upon this. This should make sure no other
architecture's !CONFIG_PCI compile breaks in the same way as parisc.
The fix had to be updated to take account of the GENERIC_PCI_IOMAP
separation.
