Pull x86 fixes from Ingo Molnar.

* 'x86-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
  x86, cpufeature: Remove stray %s, add -w to mkcapflags.pl
  x86, cpufeature: Catch duplicate CPU feature strings
  x86, cpufeature: Rename X86_FEATURE_DTS to X86_FEATURE_DTHERM
  x86: Fix kernel-doc warnings
  x86, compat: Use test_thread_flag(TIF_IA32) in compat signal delivery
