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()
