Pull x86 CPU updates from Ingo Molnar:
 "The changes in this development cycle were:

   - AMD CPU topology enhancements that are cleanups on current CPUs but
     which enable future Fam17 hardware. (Yazen Ghannam)

   - unify bugs.c and bugs_64.c (Borislav Petkov)

   - remove the show_msr= boot option (Borislav Petkov)

   - simplify a boot message (Borislav Petkov)"
