    Merge branch 'x86-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
    
    Pull x86 fixes from Ingo Molnar:
     "Half of the fixes are for various build time warnings triggered by
      randconfig builds. Most (but not all...) were harmless.
    
      There's also:
    
       - ACPI boundary condition fixes
    
       - UV platform fixes
    
       - defconfig updates
    
       - an AMD K6 CPU init fix
    
       - a %pOF printk format related preparatory change
    
       - .. and a warning fix related to the tlb/PCID changes"
