2012-03-28Add #includes needed to permit the removal of asm/system.hDavid Howells10-3/+11
asm/system.h is a cause of circular dependency problems because it contains commonly used primitive stuff like barrier definitions and uncommonly used stuff like switch_to() that might require MMU definitions. asm/system.h has been disintegrated by this point on all arches into the following common segments: (1) asm/barrier.h Moved memory barrier definitions here. (2) asm/cmpxchg.h Moved xchg() and cmpxchg() here. #included in asm/atomic.h. (3) asm/bug.h Moved die() and similar here. (4) asm/exec.h Moved arch_align_stack() here. (5) asm/elf.h Moved AT_VECTOR_SIZE_ARCH here. (6) asm/switch_to.h Moved switch_to() here. Signed-off-by: David Howells <dhowells@redhat.com>

Make asm-generic/cmpxchg.h #include asm-generic/cmpxchg-local.h as all arch files that #include the former also #include the latter. See: grep -rl asm-generic/cmpxchg-local[.]h arch/ | sort > b grep -rl asm-generic/cmpxchg[.]h arch/ | sort > a comm a b This simplifies the disintegration of asm-generic/system.h for arches that don't have their own.

2012-03-23security: optimize avc_audit() common pathLinus Torvalds1-29/+41
avc_audit() did a lot of jumping around and had a big stack frame, all for the uncommon case. Split up the uncommon case (which we really can't make go fast anyway) into its own slow function, and mark the conditional branches appropriately for the common likely case. This causes avc_audit() to no longer show up as one of the hottest functions on the branch profiles (the new "perf -b" thing), and makes the cycle profiles look really nice and dense too. The whole audit path is still annoyingly very much one of the biggest costs of name lookup, so these things are worth optimizing for. I wish we could just tell people to turn it off, but realistically we do need it: we just need to make sure that the overhead of the necessary evil is as low as possible.

2012-03-23vfs: tidy up sparse warnings in fs/namei.cLinus Torvalds1-3/+3
While doing the fs/namei.c cleanups, I ran sparse on it, and it pointed out other large integers and a couple of cases of us using '0' instead of the proper 'NULL'. Sparse still doesn't understand some of the conditional locking going on, but that's no excuse for not fixing up the trivial stuff. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

All available subchannels are now available for userspace to do with as it pleases on NVC0+.

I hope to find some decent way of addressing this too, but it's a tad tricker prior to fermi. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
