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

Pull x86 platform updates from Thomas Gleixner:
 "The platform support for x86 contains the following updates:

   - A set of updates for the UV platform to support new CPUs and to fix
     some of the UV4A BAU MRRs

   - The initial platform support for the jailhouse hypervisor to allow
     native Linux guests (inmates) in non-root cells.

   - A fix for the PCI initialization on Intel MID platforms"
