Merge tag 'x86_cpu_for_v6.14_rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull x86 cpuid updates from Borislav Petkov: - Remove the less generic CPU matching infra around struct x86_cpu_desc and use the generic struct x86_cpu_id thing - Remove magic naked numbers for CPUID functions and use proper defines of the prefix CPUID_LEAF_*. Consolidate some of the crazy use around the tree - Smaller cleanups and improvements * tag 'x86_cpu_for_v6.14_rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86/cpu: Make all all CPUID leaf names consistent x86/fpu: Remove unnecessary CPUID level check x86/fpu: Move CPUID leaf definitions to common code x86/tsc: Remove CPUID "frequency" leaf magic numbers. x86/tsc: Move away from TSC leaf magic numbers x86/cpu: Move TSC CPUID leaf definition x86/cpu: Refresh DCA leaf reading code x86/cpu: Remove unnecessary MwAIT leaf checks x86/cpu: Use MWAIT leaf definition x86/cpu: Move MWAIT leaf definition to common header x86/cpu: Remove 'x86_cpu_desc' infrastructure x86/cpu: Move AMD erratum 1386 table over to 'x86_cpu_id' x86/cpu: Replace PEBS use of 'x86_cpu_desc' use with 'x86_cpu_id' x86/cpu: Expose only stepping min/max interface x86/cpu: Introduce new microcode matching helper x86/cpufeature: Document cpu_feature_enabled() as the default to use x86/paravirt: Remove the WBINVD callback x86/cpufeatures: Free up unused feature bits
