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

Pull x86 cpu updates from Ingo Molnar:
 "Misc changes:

   - Fix nr_cpus= boot option interaction bug with logical package
     management

   - Clean up UMIP detection messages

   - Add WBNOINVD instruction detection

   - Remove the unused get_scattered_cpuid_leaf() function"

* 'x86-cpu-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
  x86/topology: Use total_cpus for max logical packages calculation
  x86/umip: Make the UMIP activated message generic
  x86/umip: Print UMIP line only once
  x86/cpufeatures: Add WBNOINVD feature definition
  x86/cpufeatures: Remove get_scattered_cpuid_leaf()
