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

Pull x86 fixes and cleanups from Thomas Gleixner:
 "This set of updates contains:

   - Robustification for the logical package managment. Cures the AMD
     and virtualization issues.

   - Put the correct start_cpu() return address on the stack of the idle
     task.

   - Fixups for the fallout of the nodeid <-> cpuid persistent mapping
     modifciations

   - Move the x86/MPX specific mm_struct member to the arch specific
     mm_context where it belongs

   - Cleanups for C89 struct initializers and useless function
     arguments"

* 'x86-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
  x86/floppy: Use designated initializers
  x86/mpx: Move bd_addr to mm_context_t
  x86/mm: Drop unused argument 'removed' from sync_global_pgds()
  ACPI/NUMA: Do not map pxm to node when NUMA is turned off
  x86/acpi: Use proper macro for invalid node
  x86/smpboot: Prevent false positive out of bounds cpumask access warning
  x86/boot/64: Push correct start_cpu() return address
  x86/boot/64: Use 'push' instead of 'call' in start_cpu()
  x86/smpboot: Make logical package management more robust
