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

Pull x86 platform updates from Ingo Molnar:
 "Two changes:

   - A Kconfig dependency fix/cleanup

   - Introduce the 'make kvmconfig' KVM configuration helper utility
     that turns the current .config into a KVM-bootable config.  Useful
     for debugging specific native kernel configs that have no KVM
     config options enabled on VM setups."

* 'x86-platform-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
  x86/platform: Make X86_GOLDFISH depend on X86_EXTENDED_PLATFORM
  x86/platform: Add kvmconfig to the phony targets
  x86, platform, kvm, kconfig: Turn existing .config's into KVM-capable configs
