Since 3.2.12 and 3.3, some systems are failing to boot with a BUG_ON.
Some other systems using the pata_jmicron driver fail to boot because no
disks are detected.  Passing pcie_aspm=force on the kernel command line
works around it.

The cause: commit 4949be16 ("PCI: ignore pre-1.1 ASPM quirking when
ASPM is disabled") changed the behaviour of pcie_aspm_sanity_check() to
always return 0 if aspm is disabled, in order to avoid cases where we
changed ASPM state on pre-PCIe 1.1 devices.

This skipped the secondary function of pcie_aspm_sanity_check which was
to avoid us enabling ASPM on devices that had non-PCIe children, causing
trouble later on.  Move the aspm_disabled check so we continue to honour
that scenario.

Now that all the slow-path code is gone from these functions, we can
inline them into the main caller - avc_has_perm_flags().

Now the compiler can see that 'avc' is allocated on the stack for this
case, which helps register pressure a bit.  It also actually shrinks the
total stack frame, because the stack frame that avc_has_perm_flags()
always needed (for that 'avc' allocation) is now sufficient for the
inlined functions too.

Inlining isn't bad - but mindless inlining of cold code (see the
previous commit) is.
Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

The selinux AVC paths remain some of the hottest (and deepest) codepaths
at filename lookup time, and we make it worse by having the slow path
cases take up I$ and stack space even when they don't trigger.  Gcc
tends to always want to inline functions that are just called once -
never mind that this might make for slower and worse code in the caller.

So this tries to improve on it a bit by making the slow-path cases
explicitly separate functions that are marked noinline, causing gcc to
at least no longer allocate stack space for them unless they are
actually called.  It also seems to help register allocation a tiny bit,
since gcc now doesn't take the slow case code into account.

Uninlining the slow path may also allow us to inline the remaining hot
path into the one caller that actually matters: avc_has_perm_flags().
I'll have to look at that separately, but both avc_audit() and
avc_has_perm_noaudit() are now small and lean enough that inlining them
may make sense.

irq_move_masked_irq() checks the return code of
chip->irq_set_affinity() only for 0, but IRQ_SET_MASK_OK_NOCOPY is
also a valid return code, which is there to avoid a redundant copy of
the cpumask. But in case of IRQ_SET_MASK_OK_NOCOPY we not only avoid
the redundant copy, we also fail to adjust the thread affinity of an
eventually threaded interrupt handler.

Handle IRQ_SET_MASK_OK (==0) and IRQ_SET_MASK_OK_NOCOPY(==1) return
values correctly by checking the valid return values seperately.

Pull btrfs fixes and features from Chris Mason:
 "We've merged in the error handling patches from SuSE.  These are
  already shipping in the sles kernel, and they give btrfs the ability
  to abort transactions and go readonly on errors.  It involves a lot of
  churn as they clarify BUG_ONs, and remove the ones we now properly
  deal with.

  Josef reworked the way our metadata interacts with the page cache.
  page->private now points to the btrfs extent_buffer object, which
  makes everything faster.  He changed it so we write an whole extent
  buffer at a time instead of allowing individual pages to go down,,
  which will be important for the raid5/6 code (for the 3.5 merge
  window ;)

  Josef also made us more aggressive about dropping pages for metadata
  blocks that were freed due to COW.  Overall, our metadata caching is
  much faster now.

  We've integrated my patch for metadata bigger than the page size.
  This allows metadata blocks up to 64KB in size.  In practice 16K and
  32K seem to work best.  For workloads with lots of metadata, this cuts
  down the size of the extent allocation tree dramatically and fragments
  much less.

  Scrub was updated to support the larger block sizes, which ended up
  being a fairly large change (thanks Stefan Behrens).

  We also have an assortment of fixes and updates, especially to the
  balancing code (Ilya Dryomov), the back ref walker (Jan Schmidt) and
  the defragging code (Liu Bo)."

Fixed up trivial conflicts in fs/btrfs/scrub.c that were just due to
removal of the second argument to k[un]map_atomic() in commit
7ac687d9.
