[GIT PULL] x86/platform changes for v3.11

[Ingo Molnar]

Linus,

Please pull the latest x86-platform-for-linus git tree from:

   git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git x86-platform-for-linus

   HEAD: cb7b80237a9f41edf2ebd899bc6a443db05578c5 x86/platform: Make X86_GOLDFISH depend on X86_EXTENDED_PLATFORM

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.

 Thanks,

	Ingo
