Merge branch 'x86-cleanups-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
* 'x86-cleanups-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
x86: Use "do { } while(0)" for empty lock_cmos()/unlock_cmos() macros
x86: Use "do { } while(0)" for empty flush_tlb_fix_spurious_fault() macro
x86, CPU: Drop superfluous get_cpu_cap() prototype
arch/x86/mm/pageattr.c: Quiet sparse noise; local functions should be static
arch/x86/kernel/ptrace.c: Quiet sparse noise
x86: Use kmemdup() in copy_thread(), rather than duplicating its implementation
x86: Replace the EVT_TO_HPET_DEV() macro with an inline function
