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
