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

Pull x86 platform changes from Ingo Molnar:
 "This tree includes assorted platform driver updates and a preparatory
  series for a platform with custom DMA remapping semantics (sta2x11 I/O
  hub)."

* 'x86-platform-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
  x86/vsmp: Fix number of CPUs when vsmp is disabled
  keyboard: Use BIOS Keyboard variable to set Numlock
  x86/olpc/xo1/sci: Report RTC wakeup events
  x86/olpc/xo1/sci: Produce wakeup events for buttons and switches
  x86, platform: Initial support for sta2x11 I/O hub
  x86: Introduce CONFIG_X86_DMA_REMAP
  x86-32: Introduce CONFIG_X86_DEV_DMA_OPS
