Merge tag 'x86-cpu-2024-05-13' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull x86 cpu updates from Ingo Molnar: - Rework the x86 CPU vendor/family/model code: introduce the 'VFM' value that is an 8+8+8 bit concatenation of the vendor/family/model value, and add macros that work on VFM values. This simplifies the addition of new Intel models & families, and simplifies existing enumeration & quirk code. - Add support for the AMD 0x80000026 leaf, to better parse topology information - Optimize the NUMA allocation layout of more per-CPU data structures - Improve the workaround for AMD erratum 1386 - Clear TME from /proc/cpuinfo as well, when disabled by the firmware - Improve x86 self-tests - Extend the mce_record tracepoint with the ::ppin and ::microcode fields - Implement recovery for MCE errors in TDX/SEAM non-root mode - Misc cleanups and fixes * tag 'x86-cpu-2024-05-13' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (34 commits) x86/mm: Switch to new Intel CPU model defines x86/tsc_msr: Switch to new Intel CPU model defines x86/tsc: Switch to new Intel CPU model defines x86/cpu: Switch to new Intel CPU model defines x86/resctrl: Switch to new Intel CPU model defines x86/microcode/intel: Switch to new Intel CPU model defines x86/mce: Switch to new Intel CPU model defines x86/cpu: Switch to new Intel CPU model defines x86/cpu/intel_epb: Switch to new Intel CPU model defines x86/aperfmperf: Switch to new Intel CPU model defines x86/apic: Switch to new Intel CPU model defines perf/x86/msr: Switch to new Intel CPU model defines perf/x86/intel/uncore: Switch to new Intel CPU model defines perf/x86/intel/pt: Switch to new Intel CPU model defines perf/x86/lbr: Switch to new Intel CPU model defines perf/x86/intel/cstate: Switch to new Intel CPU model defines x86/bugs: Switch to new Intel CPU model defines x86/bugs: Switch to new Intel CPU model defines x86/cpu/vfm: Update arch/x86/include/asm/intel-family.h x86/cpu/vfm: Add new macros to work with (vendor/family/model) values ...
