IMHO, we really only want to unmask RTEs # for PRTs we might actually use. This moves the interrupt # distribution here too. # # - When changing a vector from edge to level, call register_intr() # to do it so all the data structures get set correctly. If we # have to guess how to setup an interupt and get it wrong, this # should close some holes in changing it back to the correct type. # # - Register the HCDP interrupt in 8250_hcdp - this is where we have # to guess the polarity/trigger. The real handler will get fixed # up via PCI setup or ACPI namespace serial support, this gets it # associated w/ the port at setup.

A NULL 4th arg to semtimedop() should result in no timeout # being used (like a straight semop() call) rather than in an EFAULT error. # # The second problem was that a legitimate semtimedop() with a timeout was # also resulting in an EFAULT because the fetch of the internal timespec # strucure by sys_semtimedop() from semtimedop32()'s kernel stack was # treated as an invalid user-data reference. This requires temporarily # switching the addressing limit with set_fs(), further requiring that # appropriate parameter checking by performed prior to the switch. # # The const qualifier was removed from the (struct compat_timespec *) arg # to semtimedop32() so that the call to get_compat_timespec() wouldn't # generate a compilation warning. # -------------------------------------------- # 03/05/06 davidm@tiger.hpl.hp.com 1.971.102.36 # ia64: Manual merge of Bjorn Helgaas' sba_iommu patch to make it use seq_file. # -------------------------------------------- # 03/05/06 jejb@raven.il.steeleye.com 1.1067.1.1 # fix syntax error in ncr53c8xx from hch conversion # -------------------------------------------- # 03/05/06 greg@kroah.com 1.1063.5.1 # Merge gregkh@kernel.bkbits.net:/home/gregkh/linux/pci-2.5 # into kroah.com:/home/greg/linux/BK/pci-2.5 # -------------------------------------------- # 03/05/06 jejb@raven.il.steeleye.com 1.1067.1.2 # fix missed conversion of to_scsi_host -> dev_to_shost in sim710 # -------------------------------------------- # 03/05/06 jejb@raven.il.steeleye.com 1.1067.1.3 # add missing asm/io.h to scsi/dc395x.c # -------------------------------------------- # 03/05/06 jejb@raven.il.steeleye.com 1.1069 # Merge raven.il.steeleye.com:/home/jejb/BK/scsi-aic-2.5 # into raven.il.steeleye.com:/home/jejb/BK/scsi-misc-2.5 # -------------------------------------------- # 03/05/06 roland@frob.com 1.1063.6.1 # [PATCH] core dump psinfo.pr_sname letter fix # # This patch makes the state letter in the pr_sname field in core dumps # correct for stopped and zombie threads.

03/05/07 markh@osdl.org 1.1078 # [PATCH] New aacraid driver fixed. # # I have the new aacraid driver working on my system now. The patch is # against the 2.5.66 updates that you gave me. I made the following # changes: # # aachba.c aac_scsi_cmd() # There was a race accessing the scsicmd pointer accessing the host_lock. # I made a local pointer to the Scsi_Host so the spin_lock_irq after # aac_read wouldn't panic. I think that sometimes the I/O would be done # and the memory freed before returning invalidating the scsicmd pointer. # I made the same change in aac_io_done in case scsi_done had freed the # scsicmd memory before returning. # # comminit.c aac_alloc_comm() # AdapterFibsVirtualAddress was set to the virtual address of base. I # changed it to set it to the phys address. I compared this to code # pointed to by matt domsch on the aacraid devel list on the 5th. Its # aac_alloc_comm sets this variable to the phys address. This fixed the # probelem where the entry->addr was bad. Another was to fix it I guess # would be to leave this change alone and not try to convert the address # in aac_command_normal. # # dpcsup.c aac_response_normal() # Changed the bus_to_virt to the calculation we talked about last month. # dpcsup.c aac_command_normal() # Changed the bus_to_virt to the calculation. # -------------------------------------------- # 03/05/07 maxk@qualcomm.com 1.1063.11.4 # Merge bk://linux-bt.bkbits.net/marcel-2.5 # into qualcomm.com:/home/kernel/bt-2.5 # -------------------------------------------- # 03/05/07 torvalds@home.transmeta.com 1.1063.13.1 # Use "__attribute__" consistently. # -------------------------------------------- # 03/05/07 torvalds@home.transmeta.com 1.1063.13.2 # Allow external checkers to overrid the "cond_syscall()" macro. # -------------------------------------------- # 03/05/07 torvalds@home.transmeta.com 1.1063.13.3 # Support a "checking" mode for kernel builds, that runs a # user-supplied source checker on all C files before compiling # them. # # I'll release the actual checker once I've cleaned it up a # bit more (yay, all the copyright paperwork completed!) # -------------------------------------------- # 03/05/07 akpm@digeo.com 1.1063.13.4 # [PATCH] generic subarchitecture for ia32 # # From: Andi Kleen # # This patch adds an generic x86 subarchitecture. It is intended to provide # an dynamic interface for APIC drivers. There are already three subarchitectures # (bigsmp, summit, default) that only differ in how they drive the local APIC. # A fourth - Unisys ES7000 - is scheduled to be merged soon. # # The subarchitecture concept separated this nicely, but it has the big # drawback that they are compile time options. A Linux vendor cannot # ship own binary kernel rpms for all of these machines. Runtime probing # is needed instead. # # This patch adds a new "generic" subarchitecture that just acts as a # dynamic switching layer for APIC drivers. It only tries to virtualize # the APICs, no attempt is made to cover further incompatiblities. # This means machines like the Visual Workstation, pc9800 or # Voyager are not covered; but these are unlikely to be supported by # binary distributions anyways. # # The generic arch reuses the existing interface in mach_ipi / mach_mpparse.h / # mach_apic.h and just pulls it using some macros into an "struct genapic" # object. The main APIC code does not recognize it, it is all hidden # in the mach-generic include files. # # Auto detection of APIC types is supported in the usual way used by # existing ports like Summit - checking ACPI or mptables for specific # signatures - or it can be specified by the user using a new "apic=" # boot option. I also moved the DMI scan to before the generic # subarchitecture probe, so DMI could be used in future too to probe # specific machines. # # Some minor hacks were needed to avoid circular declaration of a few # symbols, but overall it's fairly clean. # # The patch has been tested on a Summit machine, an generic 4 virtual CPUs # Xeon and on an ES7000. # -------------------------------------------- # 03/05/07 akpm@digeo.com 1.1063.13.5 # [PATCH] Fix .altinstructions linking failures # # From: Andi Kleen # # Some configs didn't link anymore because they got references from # .altinstructions to __exit functions.

The worst offender still left is devfs_register, it's prototype # is: # # devfs_handle_t devfs_register(devfs_handle_t dir, # const char *name, unsigned int flags, # unsigned int major, unsigned int minor, # umode_t mode, void *ops, void *info) # # Of these: # # - dir and flags are always zero # - the return value is never used # - info is only used in one driver which doesn't even need it for # operation # - umode_t always describes a character device # - name very often comes from a stack buffer we sprintf'ed into # # so obviously we really want a much simpler API instead. My first draft for # this was: # # int devfs_mk_cdev(dev_t dev, umode_t mode, # struct file_operations *fops, void *info, # const char *fmt, ...) # # this removes the unused argumens, switches to a proper dev_t for the device # number and allows to directly use a printf-like expression as name, getting # rid of the temporary buffers. # # Now Al has reappeared and put the first steps of his CIDR for charater device # on public ftp and we'll soon have a similar lookup object + fops mechanism in # generic code as we already habe for blockdevices, i.e. the devfs code to # assign fops from an entry will become superflous as generic code already does # it. That means the fops and info arguments are obsolete before they were # introduced, so I'd like to propose the following API instead: # # int devfs_mk_cdev(dev_t dev, umode_t mode, const char *fmt, ...) # # which is much nicer anyway. The educated reader will notice that this is # exactly the same prototype devfs_mk_bdev has so I'll probably get suggestions # to merge those two into some kind of devfs_mk_node soon. Personally I don't # like that as character and blockdevices are two really separate entinities # and I'll like to keep them as separate as possible. # # Example patch that introduces the API and converts drivers/input attached. # # Every driver which calls devfs_mk_cdev (about 50) needs conversion. Note # that the transition can happen in pieces - devfs_register continues to work # after this patch, it's just the plan to get rid of it in the end. # -------------------------------------------- # 03/05/07 akpm@digeo.com 1.1063.13.18 # [PATCH] remove partition_name() # # From: Christoph Hellwig # # partition_name() is a variant of __bdevname() that caches results and # returns a pointrer to kmalloc()ed data instead of printing into a buffer. # Due to it's caching it gets utterly confused when the name for a dev_t # changes (can happen easily now with device mapper and probably in the # future with dynamic dev_t users). # # It's only used by the raid code and most calls are through a wrapper, # bdev_partition_name() which takes a struct block_device * that maybe be # NULL. # # The patch below changes the bdev_partition_name() to call bdevname() if # possible and the other calls where we really have nothing more than a dev_t # to __bdevname. # # Btw, it would be nice if someone who knows the md code a bit better than me # could remove bdev_partition_name() in favour of direct calls to bdevname() # where possible - that would also get rid of the returns pointer to string # on stack issue that this patch can't fix yet. # -------------------------------------------- # 03/05/07 akpm@digeo.com 1.1063.13.19 # [PATCH] switch most remaining drivers over to devfs_mk_bdev # # From: Christoph Hellwig # # This is a pretty huge patch, but splitting it doesn't make a lot # of sense.. # # (USB may still need work) # -------------------------------------------- # 03/05/07 akpm@digeo.com 1.1063.13.20 # [PATCH] dvbdev fixes # # From: Monchi Abbad # # I found a mistake in the dvbdev.c file when creating the dvb /devfs files, # it created /dev/dvb/adapter0device0 instead of /dev/dvb/adapter0/device0. # But here is a simple fix. # -------------------------------------------- # 03/05/07 akpm@digeo.com 1.1063.13.21 # [PATCH] access_ok() race fix for 80386. # # From: Manfred Spraul # # Real 80386 cpus ignore the write protected bit in the page tables when # running in supervisory mode. Thus the write protected bit must be checked by # software. The current implementation does that check during access_ok(). # This can result in data corruptions, if kswapd starts a swap-out between the # access_ok and the actual write operation. # # To fix this, the patch moves the check from access_ok() into # __copy_to_user_ll(), and redirects all user space writes into # __copy_to_user_ll(). The patch only affects kernels build for 80386 cpus. # Additionally, the patch removes the dead prototypes for __put_user_{1,2,4,8}. # # Due to the uninlining of access_ok, the .text segment is now ~ 8 kB shorter. # -------------------------------------------- # 03/05/07 akpm@digeo.com 1.1063.13.22 # [PATCH] hold i_sem on swapfiles # # If a swapfile is ftruncated while in use, subsequent swapout will scribble on # the filesystem. # # This is a case of root-shoot-foot, but wrecking the fs is a fairly rude # response.

I ended up putting the accounting into a stack-local # structure which is pointed to by current->reclaim_state. # # One reason for this is that we can cleanly resurrect the current->local_pages # pool by putting it into struct reclaim_state. # # (current->local_pages was removed because the per-cpu page pools in the page # allocator largely duplicate its function.

But after the semaphore set is removed from the ID array by # calling sem_rmid(), there is no lock to protect the waiting queue for # that semaphore set. So, if a waiter is woken up by a signal (not by the # wakeup from freeary()), it will check the q->status and q->prev fields. # At that moment, freeary() may not have a chance to update those fields # yet. # # static void freeary (int id) # { # ....... # sma = sem_rmid(id); # # ...... # /* Wake up all pending processes and let them fail with EIDRM.*/ # for (q = sma->sem_pending; q; q = q->next) { # q->status = -EIDRM; # q->prev = NULL; # wake_up_process(q->sleeper); /* doesn't sleep */ # } # sem_unlock(sma); # ...... # } # # So I propose move sem_rmid() after the loop of waking up every waiters. # That could gurantee that when the waiters are woke up, the updates for # q->status and q->prev have already done.

It was broken in 2.5.68 IIRC. # -------------------------------------------- # 03/05/12 akpm@digeo.com 1.1063.1.64 # [PATCH] fix for clusterd io_apics # # From: Keith Mannthey # # The following is a patch to fix inconsistent use of the function # set_ioapic_affinity. In the current kernel it is unclear as to weather the # value being passed to the function is a cpu mask or valid apic id. In # irq_affinity_write_proc the kernel passes on a cpu mask but the kirqd thread # passes on logical apic ids. In flat apic mode this is not an issue because a # cpu mask represents the apic value. However in clustered apic mode the cpu # mask is very different from the logical apic id. # # This is an attempt to do the right thing for clustered apics. I clarify that # the value being passed to set_ioapic_affinity is a cpu mask not a apicid. # Set_ioapic_affinity will do the conversion to logical apic ids. Since many # cpu masks don't map to valid apicids in clustered apic mode TARGET_CPUS is # used as a default value when such a situation occurs. I think this is a good # step in making irq_affinity clustered apic safe. # -------------------------------------------- # 03/05/12 akpm@digeo.com 1.1063.1.65 # [PATCH] provide user feedback for emergency sync and remount # # People like to see when the emergency sync and emergency remount operations # have completed. # -------------------------------------------- # 03/05/12 akpm@digeo.com 1.1063.1.66 # [PATCH] copy_process return value fix # # Rather than assuming that all the things which copy_process() calls want to # return -ENOMEM, correctly propagate the return values. # # This turns out to be a no-op at present. # -------------------------------------------- # 03/05/12 akpm@digeo.com 1.1063.1.67 # [PATCH] de_thread memory corruption fix # # From: Manfred Spraul # # de_thread calls list_del(¤t->tasks), but current->tasks was never # added to the task list.

As things stand, # the presence of a vm_area in the vmlist protects from allocators other than # the owner examining the ptes in that area. This puts an ordering constraint # on unmapping, so that allocators are required to unmap areas before removing # them from the list or otherwise dropping the lock. # # Currently, unmap_vm_area() is done outside the lock and after the area is # removed, which as we've seen from Felix von Leitner's test is oopsable. # # The following patch folds calls to unmap_vm_area() into remove_vm_area() to # reinstate what are essentially the 2.4.x semantics of vfree(). This renders # a number of unmap_vm_area() calls unnecessary (and in fact oopsable since # they wipe ptes from later allocations). It's an open question as to whether # this is sufficiently performant, but it is the minimally invasive approach. # The more performant alternative is to provide the right API hooks to wipe the # vmalloc() area clean before removing them from the list, using the ownership # of the area to eliminate holding the vmlist_lock for the duration of the # unmapping. If it proves to be necessary wli is on standby to implement it. # -------------------------------------------- # 03/05/12 akpm@digeo.com 1.1063.1.69 # [PATCH] Reserve the ext2/ext3 EAs for the Lustre filesystem # # From: Andreas Dilger # # Below are the patches which reserve the Lustre EA index.
