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:

   - fix the s2ram regression related to confusion around segment
     register restoration, plus related cleanups that make the code more
     robust

   - a guess-unwinder Kconfig dependency fix

   - an isoimage build target fix for certain tool chain combinations

   - instruction decoder opcode map fixes+updates, and the syncing of
     the kernel decoder headers to the objtool headers

   - a kmmio tracing fix

   - two 5-level paging related fixes

   - a topology enumeration fix on certain SMP systems"

* 'x86-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
  objtool: Resync objtool's instruction decoder source code copy with the kernel's latest version
  x86/decoder: Fix and update the opcodes map
  x86/power: Make restore_processor_context() sane
  x86/power/32: Move SYSENTER MSR restoration to fix_processor_context()
  x86/power/64: Use struct desc_ptr for the IDT in struct saved_context
  x86/unwinder/guess: Prevent using CONFIG_UNWINDER_GUESS=y with CONFIG_STACKDEPOT=y
  x86/build: Don't verify mtools configuration file for isoimage
  x86/mm/kmmio: Fix mmiotrace for page unaligned addresses
  x86/boot/compressed/64: Print error if 5-level paging is not supported
  x86/boot/compressed/64: Detect and handle 5-level paging at boot-time
  x86/smpboot: Do not use smp_num_siblings in __max_logical_packages calculation
