Merge branch 'x86-cleanups-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull x86 cleanup patches from Ingo Molnar:
"Misc smaller cleanups"
* 'x86-cleanups-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
x86: ptrace.c only needs export.h and not the full module.h
x86, apb_timer: remove unused variable percpu_timer
um: don't compare a pointer to 0
arch/x86/platform/uv: use ARRAY_SIZE where possible
