Merge branch 'x86-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip

Pull x86 fixes from Peter Anvin:
 "A collection of small fixes:

   - There still seem to be problems with asm goto which requires the
     empty asm hack.
   - If SMAP is disabled at compile time, don't enable it nor try to
     interpret a page fault as an SMAP violation.
   - Fix a case of unbounded recursion while tracing"

* 'x86-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
  x86, smap: smap_violation() is bogus if CONFIG_X86_SMAP is off
  x86, smap: Don't enable SMAP if CONFIG_X86_SMAP is disabled
  compiler/gcc4: Make quirk for asm_volatile_goto() unconditional
  x86: Use preempt_disable_notrace() in cycles_2_ns()
