If qla2x00_probe_one()'s call to qla2x00_iospace_config() fails, we call
qla2x00_free_device() to clean up. But because ha->dpc_pid hasn't been set
yet, qla2x00_free_device() tries to stop a kernel thread which hasn't started
yet. It does wait_for_completion() against an uninitialised completion struct
and the kernel hangs up.
Fix it by initialising ha->dpc_pid a bit earlier.

The main problem fixes is that in certain situations stopping md arrays may
take longer than you expect, or may require multiple attempts. This would
only happen when resync/recovery is happening.
This patch fixes three vaguely related bugs.
1/ The recent change to use kthreads got the setting of the
process name wrong. This fixes it.
2/ The recent change to use kthreads lost the ability for
md threads to be signalled with SIG_KILL. This restores that.
3/ There is a long standing bug in that if:
- An array needs recovery (onto a hot-spare) and
- The recovery is being blocked because some other array being
recovered shares a physical device and
- The recovery thread is killed with SIG_KILL
Then the recovery will appear to have completed with no IO being
done, which can cause data corruption.
This patch makes sure that incomplete recovery will be treated as
incomplete.
Note that any kernel affected by bug 2 will not suffer the problem of bug
3, as the signal can never be delivered. Thus the current 2.6.14-rc
kernels are not susceptible to data corruption. Note also that if arrays
are shutdown (with "mdadm -S" or "raidstop") then the problem doesn't
occur. It only happens if a SIGKILL is independently delivered as done by
'init' when shutting down.

Changes all spinlocks that can be held during an irq handler to disable

In raw1394.c:handle_iso_listen(), don't grab host_info_lock at all -- we're
not accessing host_info_list or host_count, and holding this lock while
trying to tasklet_kill the iso tasklet this can cause an ABBA deadlock if
ohci:dma_rcv_tasklet is running and tries to grab host_info_lock in

Reported by: Bob Tracy <rct@gherkin.frus.com>
"...I've got a Toshiba notebook (730XCDT -- Pentium 150MMX) for which
I'm using the Vesa FB driver. When the machine has been idle for some
time and the driver attempts to powerdown the display, rather than the
display going blank, it goes gray with several strange lines. When I
hit the "shift" key or other-wise wake up the display, the old video
state is not fully restored..."
vesafb recently added a blank method which has only 2 states, powerup and
powerdown. The powerdown state is used for all blanking levels, but in his
case, powerdown does not work correctly for higher levels of display
powersaving. Thus, for intermediate power levels, use software blanking,
and use only hardware blanking for an explicit powerdown.

During the development of an USB device I found a bug in the handling of
Highspeed HID devices in the kernel.
What happened?
Highspeed HID devices are correctly recognized and enumerated by the
kernel. But even if usbhid kernel module is loaded, no HID reports are
received by the kernel.
The output of the hardware USB analyzer told me that the host doesn't
even poll for interrupt IN transfers (even the "interrupt in" USB
transfer are polled by the host).
After some debugging in hid-core.c I've found the reason.
In case of a highspeed device, the endpoint interval is re-calculated in
driver/usb/input/hid-core.c:
line 1669:
/* handle potential highspeed HID correctly */
interval = endpoint->bInterval;
if (dev->speed == USB_SPEED_HIGH)
interval = 1 << (interval - 1);
Basically this calculation is correct (refer to USB 2.0 spec, 9.6.6).
This new calculated value of "interval" is used as input for
usb_fill_int_urb:
line 1685:
usb_fill_int_urb(hid->urbin, dev, pipe, hid->inbuf, 0,
hid_irq_in, hid, interval);
Unfortunately the same calculation as above is done a second time in
usb_fill_int_urb in the file include/linux/usb.h:
line 933:
if (dev->speed == USB_SPEED_HIGH)
urb->interval = 1 << (interval - 1);
else
urb->interval = interval;
This means, that if the endpoint descriptor (of a high speed device)
specifies e.g. bInterval = 7, the urb->interval gets the value:
hid-core.c: interval = 1 << (7-1) = 0x40 = 64
urb->interval = 1 << (interval -1) = 1 << (63) = integer overflow
Because of this the value of urb->interval is sometimes negative and is
rejected in core/urb.c:
line 353:
/* too small? */
if (urb->interval <= 0)
return -EINVAL;
The conclusion is, that the recalculaton of the interval (which is
necessary for highspeed) should not be made twice, because this is
simply wrong. ;-)
Re-calculation in usb_fill_int_urb makes more sense, because it is the
most general approach. So it would make sense to remove it from
hid-core.c.
Because in hid-core.c the interval variable is only used for calling
usb_fill_int_urb, it is no problem to remove the highspeed
re-calculation in this file.

Increased use of scatter-gather by usb-storage driver after 2.6.13 has
exposed a buggy codepath in isp116x-hcd, which was probably never
visited before: bug happened only for those urbs, for which
URB_SHORT_NOT_OK was set AND short transfer occurred.
The fix attached was tested in 2 ways: (a) it fixed failing
initialization of a flash drive with an embedded hub; (b) the fix was
tested with 'usbtest' against a modified g_zero driver (on top of
net2280), which generated short bulk IN transfers of various lengths
including multiples and non-multiples of max_packet_length.

Fix bug 5441.
I didn't know about messy programs like svgatextmode... Couldn't this be
integrated in some linux/drivers/video/console/svgacon.c ?... So because
of the existence of the svgatextmode program, the kernel is not supposed to
touch to CRT_OVERFLOW/SYNC_END/DISP/DISP_END/OFFSET ?
Disabling the check in vgacon_resize() might help indeed, but I'm really
not sure whether it will work for any chipset: in my patch, CRT registers
are set at each console switch, since stty rows/cols apply to consoles
separately...
The attached solution is to keep the test, but if it fails, we assume that
the caller knows what it does (i.e. it is svgatextmode) and then disable
any further call to vgacon_doresize. Svgatextmode is usually used to
_expand_ the display, not to shrink it. And it is harmless in the case of
a too big stty rows/cols: the display will just be cropped. I tested it on
my laptop, and it works fine with svgatextmode.
A better solution would be that svgatextmode explicitely tells the kernel
not to care about video timing, but for this an interface needs be defined
and svgatextmode be patched.

Juan was kind enough to linger on site, and work on a production
machine, to try the parameter to make the system stable. He discovered
that reducing the maximum transfer size issued to the adapter to 128KB
stabilized his system. This is related to an earlier change for the
2.6.13 tree resulting from Martin Drab's testing where the transfer size
was reduced from 4G to 256KB; we needed to go still further in scaling
back the request size.
Here is the patch that tames this regression.

The aironet PCI driver has a build dependency on ISA that prevent the
driver to compile on systems that doesn't support ISA, like x86_64. The
driver really doesn't depend on ISA, it does some ISA stuff in the
initialization code, since the driver supports both ISA and PCI cards. So
the driver should depend on ISA_DMA_API to build on all systems, and this
will not hurt PCI at all.

Patch from Lothar Wassmann
The function serial_pxa_set_termios() is calling uart_update_timeout()
with the baud rate divisor as third parameter, while
uart_update_timeout() expects the baud rate in this place.
This results in a bogus port->timeout which is proportional to the
baud rate.

In the current dell_rbu code ver 2.0 the packet update mechanism makes the
user app dump every individual packet in to the driver.
This adds in efficiency as every packet update makes the
/sys/class/firmware/dell_rbu/loading and data files to disappear and reappear
again. Thus the user app needs to wait for the files to reappear to dump
another packet. This slows down the packet update tremendously in case of
large number of packets. I am submitting a new patch for dell_rbu which will
change the way we do packet updates;
In the new method the user app will create a new single file which has already
packetized the rbu image and all the packets are now staged in this file.
This driver also creates a new entry in
/sys/devices/platform/dell_rbu/packet_size ; the user needs to echo the packet
size here before downloading the packet file.
The user should do the following:
create one single file which has all the packets stacked together.
echo the packet size in to /sys/devices/platform/dell_rbu/packet_size.
echo 1 > /sys/class/firmware/dell_rbu/loading
cat the packetfile > /sys/class/firmware/dell_rbu/data
echo 0 > /sys/class/firmware/dell_rbu/loading
The driver takes the file which came through /sys/class/firmware/dell_rbu/data
and takes chunks of paket_size data from it and place in contiguous memory.
This makes packet update process very efficient and fast. As all the packet
update happens in one single operation. The user can still read back the
downloaded file from /sys/devices/platform/dell_rbu/data.

If a process issues an URB from userspace and (starts to) terminate
before the URB comes back, we run into the issue described above. This
is because the urb saves a pointer to "current" when it is posted to the
device, but there's no guarantee that this pointer is still valid
afterwards.
In fact, there are three separate issues:
1) the pointer to "current" can become invalid, since the task could be
completely gone when the URB completion comes back from the device.
2) Even if the saved task pointer is still pointing to a valid task_struct,
task_struct->sighand could have gone meanwhile.
3) Even if the process is perfectly fine, permissions may have changed,
and we can no longer send it a signal.
So what we do instead, is to save the PID and uid's of the process, and
introduce a new kill_proc_info_as_uid() function.

The logic in ide_do_request() doesn't guarantee that both drives will be
serviced after a call. It may "forget" to service one in some
circumstances, including when one of the drive is suspended (it will
eventually fail to service the slave when the master is suspended for
example). This prevents the wakeup requests that gets queued on wakeup
from sleep from beeing serviced in some cases when 2 drives are sharing
an IDE bus.
The problem is deep enough in the way this code works (and there are
probably a few other problematic but rare corner cases) and fixing it
would require some major rethinking of the way IDE decides which channel
to service. This is not 2.6.14 material. However, in the meantime,
Bart has accepted this simple workaround that will fix the crash on
wakeup from sleep since this specific corner case is actually hitting
users to get into 2.6.14.

Unfortunately, [your patch] might address the crash but doesn't address
the real problem. It turns out that the problem is one of padding
(the firmware cksum engine works only on 32-bit chunks, yuck), so
the special casing for length == 1 wasn't sufficient anyway.
This patch addresses the issue, as well the other issue of i386 +
CONFIG_HIGHMEM being broken. It is pretty much the same workaround
that Adaptec themselves used in their Windows driver. I have yet to
check if it fixes the problem when the skb is non-linear, but this
patch _will_ solve the problem for 99% of the users out there (those
not using sendfile).

The following patch renames __in_dev_get() to __in_dev_get_rtnl() and
introduces __in_dev_get_rcu() to cover the second case.
1) RCU with refcnt should use in_dev_get().
2) RCU without refcnt should use __in_dev_get_rcu().
3) All others must hold RTNL and use __in_dev_get_rtnl().
There is one exception in net/ipv4/route.c which is in fact a pre-existing
race condition. I've marked it as such so that we remember to fix it.

There's a problem in our host release in that it calls
scsi_proc_hostdir_rm(). However, if you hold a reference to the host as
you remove the module, the host template (which proc uses) will be freed

Fix this by moving scsi_proc_hostdir_rm() to where it should be: in
scsi_remove_host().

This adds suspend support for the Radeon M11 chip in 12" iBooks

have that chip, so they might also be supported.
The chip identifies itself as "RV350 NV" (pci id 0x4e56), revision 0x80.
Apple calls it "Snowy", xfree86 names it "ATI FireGL Mobility T2 (M11)
NV (AGP)". So, we seem to be lucky here: The suspend-code for the M10

Set serialize_io=1 by default. This is safer and required by seemingly more
and more hardware. It causes little or no performance loss for S400 devices.
Performance of S800 1394b devices may drop by 25...30%. Therefore make the
parameter's description and dmesg message clearer about performance impact.
Update description of the max_speed parameter too. IEEE1394_SPEED_MAX is

Fixes for deadlocks of the ieee1394 and scsi subsystems and long delays in
futile error recovery attempts when SBP-2 devices are removed or drivers are
unloaded.
- Complete commands quickly with DID_NO_CONNECT if the 1394 node is gone or if
the 1394 low-level driver was unloaded.
- Skip unnecessary work in the eh_abort_handler and eh_device_reset_handler if
the node or 1394 low-level driver is gone.
- Let scsi's high-level shut down gracefully when sbp2 is being unloaded or
detached from the 1394 unit. A call to scsi_remove_device is added for this
purpose, which requires us to store a scsi_device pointer.
- scsi_device pointer is obtained from slave_alloc hook and cleared by
slave_destroy. This avoids usage of the pointer after the scsi device was
deleted e.g. by the user via scsi_mod's sysfs interface.

This change removes a bogus error message from the IOC4 serial driver
interrupt handler.
This error message is bogus for two reasons. First, it can never occur
given that current code takes care to initialize IOC4 in such a way that
these "unknown" interrupts could never occur. Second, this code fails to
take into account that other drivers can share the IOC4 interrupt mechanism
through SA_SHIRQ, and thus this driver is not in-fact "all-knowing".
Finally, this error message triggers every time some "unknown" interrupt
occurs -- it's not rate limited or repetition limited in any way, thereby
effectively denying use of the console device. Given its bogosity in the
first place, it's best to just get rid of it entirely.

The SMU driver has a small mistake in the locking of the interrupt code,

When creating a multipath device, if the queue_if_no_path parameter is
specified it gets ignored.
While the queue_if_no_path variable is correctly set to 1, the
saved_queue_if_no_path gets set to 0. When the device is subsequently made
live (resumed), the saved value (0) always overwrites the live value (1) so
the option *always* gets turned off.
The fix adds a parameter to the queue_if_no_path() function to indicate
whether the previous value should be preserved or not - if not, as when the
device is being set up, the saved value is set to the new value (1).

Fix 5780 PHY related problems:
1. MAC_RX_MODE reset must be done before setting up the MAC_MODE
register on 5705_PLUS chips or the chip will stop receiving after
a while. The MAC_RX_MODE reset is needed to prevent intermittently
losing the first receive packet on serdes chips.
2. Skip MAC loopback test on 5780 because of hardware errata. Normal
traffic including PHY loopback is not affected by the errata.
3. PHY loopback fails intermittently on 5708S and this is fixed by
putting the PHY in loopback mode first before programming the MAC
mode register. A MAC_RX_MODE reset is also added.
4. Return -EINVAL in tg3_nway_reset() if device is in TBI mode. Allow
nway_reset if 5780S is in parallel detect mode.

Received from Mark Salyzyn from Adaptec.
High Priority Queues have *never* been used in the entire history of the
aac based adapters. Associated with this, aac_insert_entry can be
removed, SavedIrql can be removed & padding variable can be removed.
With the movement of SavedIrql out & replaced with an automatic variable
qflags, the locking can be refined somewhat. The sparse warnings did not
catch the need for byte swapping in the 'dprintk' debugging print
macros, so fixed this up when this code was moved outside of the now
refined locking.

In the rare instances where the adapter, or the motherboard, is
misbehaving; driver initialization or shutdown becomes problematic. By
introducing a 3 minute timeout on the first interrupt driven command
during initialization, or the issuance of the adapter shutdown command
during driver unload, we can resolve the lockup problems induced by
common (but rare) hardware misbehaviors.
The timeout during initialization, should it occur, is accompanied by a
message presented to the console and the logs indicating that the user
should inspect and resolve problems with interrupt routing.
