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

Pull x86 fixes from Ingo Molnar:
 "Misc fixes from all around the map, plus a commit that introduces a
  new header of Intel model name symbols (unused) that will make the
  next merge window easier"

* 'x86-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
  x86/ioapic: Fix incorrect pointers in ioapic_setup_resources()
  x86/entry/traps: Don't force in_interrupt() to return true in IST handlers
  x86/cpu/AMD: Extend X86_FEATURE_TOPOEXT workaround to newer models
  x86/cpu/intel: Introduce macros for Intel family numbers
  x86, build: copy ldlinux.c32 to image.iso
  x86/msr: Use the proper trace point conditional for writes
