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

Pull x86 fixes from Ingo Molnar:
 "Two fixes:

   - A PCID related revert that fixes power management and performance
     regressions.

   - The module loader robustization and sanity check commit is rather
     fresh, but it looked like a good idea to apply because of the
     hidden data corruption problem such invalid modules could cause"
