Merge branch 'x86-cpu-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull x86 topology discovery improvements from Ingo Molnar: "These changes improve topology discovery on AMD CPUs. Right now this feeds information displayed in /sys/devices/system/cpu/cpuX/cache/indexY/* - but in the future we could use this to set up a better scheduling topology." * 'x86-cpu-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86, cacheinfo: Base cache sharing info on CPUID 0x8000001d on AMD x86, cacheinfo: Make use of CPUID 0x8000001d for cache information on AMD x86, cacheinfo: Determine number of cache leafs using CPUID 0x8000001d on AMD x86: Add cpu_has_topoext
