      Increase OSF partition limit from 8 to 18 · 34d211a2
      由 Linus Torvalds 提交于 
      It turns out that while a maximum of 8 partitions may be what people
"should" have had, you can actually fit up to 18 entries(*) in a sector.

And some people clearly were taking advantage of that, like Michael
Cree, who had ten partitions on one of his OSF disks.

(*) The OSF partition data starts at byte offset 64 in the first sector,
    and the array of 16-byte partition entries start at offset 148 in
    the on-disk partition structure.

      prune back iprune_sem · bab1d944
      由 Christoph Hellwig 提交于 
      iprune_sem is continously giving us lockdep warnings because we do take it in
read mode in the reclaim path, but we're also doing non-NOFS allocations under
it taken in write mode.

Taking a bit deeper look at it I think it's fixable quite trivially:

 - for invalidate_inodes we do not need iprune_sem at all.  We have an active
   reference on the superblock, so the filesystem is not going away until it
   has finished.
 - for evict_inodes we do need it, to make sure prune_icache has done it's
   work before we tear down the superblock.  But there is no reason to
   hold it over the actual reclaim operation - it's enough to cycle through
   it after the actual reclaim to make sure we wait for any pending
   prune_icache to complete.  We just have to remove the WARN_ON for
   otherwise busy inodes as they can actually happen now.

      x86, AMD: Set ARAT feature on AMD processors · b87cf80a
      由 Boris Ostrovsky 提交于 
      Support for Always Running APIC timer (ARAT) was introduced in
commit db954b58. This feature
allows us to avoid switching timers from LAPIC to something else
(e.g. HPET) and go into timer broadcasts when entering deep
C-states.

AMD processors don't provide a CPUID bit for that feature but
they also keep APIC timers running in deep C-states (except for
cases when the processor is affected by erratum 400). Therefore
we should set ARAT feature bit on AMD CPUs.

      x86, quirk: Fix SB600 revision check · 1d3e09a3
      由 Andreas Herrmann 提交于 
      Commit 7f74f8f2
(x86 quirk: Fix polarity for IRQ0 pin2 override on SB800
systems) introduced a regression. It removed some SB600 specific
code to determine the revision ID without adapting a
corresponding revision ID check for SB600.

See this mail thread:

  http://marc.info/?l=linux-kernel&m=129980296006380&w=2

This patch adapts the corresponding check to cover all SB600
revisions.
