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:

   - one to quirk-save/restore certain system MSRs across
     suspend/resume, to make certain Intel systems work better
     (Chen Yu)

   - and also to constify a read only structure (Julia Lawall)"
