  I've run allmodconfig builds on a bunch of target, FWIW (essentially the
  same patch).  Note that these includes are recent addition caused by added
  inline function that had since then become a define.  So while I agree with
  your comments in general, in _this_ case it's pretty safe.

  The commit that had done it is 3062fc67
  ("memcontrol: move mm_cgroup to header file") and the switch to #define
  is in commit 60c12b12 ("memcontrol: add
  vm_match_cgroup()") (BTW, that probably warranted mentioning in the
  changelog of the latter).

When we free a page via free_huge_page and we detect that we are in surplus
the page will be returned to the buddy.  After this we no longer own the page.

However at the end free_huge_page we clear out our mapping pointer from
page private.  Even where the page is not a surplus we free the page to
the hugepage pool, drop the pool locks and then clear page private.  In
either case the page may have been reallocated.  BAD.

Make sure we clear out page private before we free the page.

I added a nasty local variable shadowing bug to fuse in 2.6.24, with the
result, that the 'default_permissions' mount option is basically ignored.

How did this happen?

 - old err declaration in inner scope
 - new err getting declared in outer scope
 - 'return err' from inner scope getting removed
 - old declaration not being noticed

-Wshadow would have saved us, but it doesn't seem practical for
the kernel :(

More testing would have also saved us :((

2.6.25-rc1 percpu changes broke CONFIG_DEBUG_PREEMPT's per_cpu checking
on several architectures.  On s390, sparc64 and x86 it's been weakened to
not checking at all; whereas on powerpc64 it's become too strict, issuing
warnings from __raw_get_cpu_var in io_schedule and init_timer for example.

Fix this by weakening powerpc's __my_cpu_offset to use the non-checking
local_paca instead of get_paca (which itself contains such a check);
and strengthening the generic my_cpu_offset to go the old slow way via
smp_processor_id when CONFIG_DEBUG_PREEMPT (debug_smp_processor_id is
where all the knowledge of what's correct when lives).

During the last step of hibernation in the "platform" mode (with the
help of ACPI) we use the suspend code, including the devices'
->suspend() methods, to prepare the system for entering the ACPI S4
system sleep state.

But at least for some devices the operations performed by the
->suspend() callback in that case must be different from its operations
during regular suspend.

For this reason, introduce the new PM event type PM_EVENT_HIBERNATE and
pass it to the device drivers' ->suspend() methods during the last phase
of hibernation, so that they can distinguish this case and handle it as
appropriate.  Modify the drivers that handle PM_EVENT_SUSPEND in a
special way and need to handle PM_EVENT_HIBERNATE in the same way.

These changes are necessary to fix a hibernation regression related
to the i915 driver (ref. http://lkml.org/lkml/2008/2/22/488).

The clear nexus I_T and clear nexus I_T_L functions in the aic94xx
specify the SUSPEND_TX flag which causes the sequencer to be suspended
until it receives a RESUME_TX.  Unfortunately, nothing ever sends the
resume, so the sequencer on the link is stopped forever, leading to
eventual timeouts and I/O errors.

Since clear nexus commands are only executed as part of error recovery,
it's perfectly fine to keep the sequencer running on the link ... as
soon as the recovery function is completed, we'll send it the commands
to retry.

stex_internal_copy copies an in-kernel buffer to a sg list by using
scsi_kmap_atomic_sg. Some functions calls stex_internal_copy with
sg_count in struct st_ccb, which is the value that dma_map_sg
returned. However it might be shorter than the actual number of sg
entries (if the IOMMU merged the sg entries).

scsi_kmap_atomic_sg doesn't see sg->dma_length so stex_internal_copy
should be called with the actual number of sg entries
(i.e. scsi_sg_count), because if the sg entries were merged,
stex_direct_copy wrongly think that the data length in the sg list is
shorter than the actual length.

stex_direct_copy copies an in-kernel buffer to a sg list in order to
spoof some SCSI commands. stex_direct_copy calls dma_map_sg and then
stex_internal_copy with the value that dma_map_sg returned. It calls
scsi_kmap_atomic_sg to copy data.

scsi_kmap_atomic_sg doesn't see sg->dma_length so if dma_map_sg merges
sg entries, stex_internal_copy gets the smaller number of sg entries
than the acutual number, which means it wrongly think that the data
length in the sg list is shorter than the actual length.

stex_direct_copy shouldn't call dma_map_sg and it doesn't need since
this code path doesn't involve dma transfers. This patch removes
stex_direct_copy and simply calls stex_internal_copy with the actual
number of sg entries.

The libsas error handler has two fairly fatal bugs

1. scsi_sas_task_done calls scsi_eh_finish_cmd() too early.  This
   happens if the task completes after it has been aborted but before
   the error handler starts up.  Because scsi_eh_finish_cmd()
   decrements host_failed and adds the task to the done list, the
   error handler start check (host_failed == host_busy) never passes
   and the eh never starts.

2. The multiple task completion paths sas_scsi_clear_queue_... all
   simply delete the task from the error queue.  This causes it to
   disappear into the ether, since a command must be placed on the
   done queue to be finished off by the error handler.  This behaviour
   causes the HBA to hang on pending commands.

Fix 1. by moving the SAS_TASK_STATE_ABORTED check to an exit clause at
the top of the routine and calling ->scsi_done() unconditionally (it
is a nop if the timer has fired).  This keeps the task in the error
handling queue until the eh starts.

Fix 2. by making sure every task goes through task complete followed
by scsi_eh_finish_cmd().

Tested this by firing resets across a disk running a hammer test (now
it actually survives without hanging the system)
