 "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
