Jiri Pirko 0bd80dad57 net: get rid of multiple bond-related netdevice->priv_flags
Now when bond-related code is moved from net/core/dev.c into bonding
code, multiple priv_flags are not needed anymore. So let them rot.

Jiri Pirko f1c1775ac7 bonding: register slave pointer for rx_handler
Register slave pointer as rx_handler data. That would eventually prevent
need to loop over slave devices to find the right slave.

Use synchronize_net to ensure that bond_handle_frame does not get slave
structure freed when working with that.

Eric B Munson bb6405eab2 Documentation: update cgroup pid and cpuset information
The cgroup documentation does not specify how a process can be removed
from a particular group.  This patch adds a note at the end of the
simple example about how this is done.  Also, some cgroups (like
cpusets) require user input before a new group can be used.  This is
noted in the patch as well.

Thomas Graf 400b871ba6 netfilter ebtables: fix xt_AUDIT to work with ebtables
Even though ebtables uses xtables it still requires targets to
return EBT_CONTINUE instead of XT_CONTINUE. This prevented
xt_AUDIT to work as ebt module.

Upon Jan's suggestion, use a separate struct xt_target for
NFPROTO_BRIDGE having its own target callback returning
EBT_CONTINUE instead of cloning the module.

Linus Torvalds 34d211a2d5 Increase OSF partition limit from 8 to 18
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.

Christoph Hellwig bab1d9444d prune back iprune_sem
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.

Boris Ostrovsky b87cf80af3 x86, AMD: Set ARAT feature on AMD processors
Support for Always Running APIC timer (ARAT) was introduced in
commit db954b5898. 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.

Andreas Herrmann 1d3e09a304 x86, quirk: Fix SB600 revision check
Commit 7f74f8f28a
(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.
