Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/x86/linux-2.6-generic-bitops-v3
* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/x86/linux-2.6-generic-bitops-v3: x86, bitops: select the generic bitmap search functions x86: include/asm-x86/pgalloc.h/bitops.h: checkpatch cleanups - formatting only x86: finalize bitops unification x86, UML: remove x86-specific implementations of find_first_bit x86: optimize find_first_bit for small bitmaps x86: switch 64-bit to generic find_first_bit x86: generic versions of find_first_(zero_)bit, convert i386 bitops: use __fls for fls64 on 64-bit archs generic: implement __fls on all 64-bit archs generic: introduce a generic __fls implementation x86: merge the simple bitops and move them to bitops.h x86, generic: optimize find_next_(zero_)bit for small constant-size bitmaps x86, uml: fix uml with generic find_next_bit for x86 x86: change x86 to use generic find_next_bit uml: Kconfig cleanup uml: fix build error
