Subject: [GIT PULL] x86 cleanups for v3.9
Linus,
Please pull the latest x86-cleanups-for-linus git tree from:
git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git x86-cleanups-for-linus
HEAD: 19348e749e9515c429f5d561d2f2c724862a4bee x86: ptrace.c only needs export.h and not the full module.h
Misc smaller cleanups.
Thanks,
Ingo

arch/x86/platform/uv: use ARRAY_SIZE where possible
um: don't compare a pointer to 0
x86, apb_timer: remove unused variable percpu_timer
