Merge tag 'x86_cpu_for_v6.11_rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull x86 cpu model updates from Borislav Petkov: - Flip the logic to add feature names to /proc/cpuinfo to having to explicitly specify the flag if there's a valid reason to show it in /proc/cpuinfo - Switch a bunch of Intel x86 model checking code to the new CPU model defines - Fixes and cleanups * tag 'x86_cpu_for_v6.11_rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86/cpu/intel: Drop stray FAM6 check with new Intel CPU model defines x86/cpufeatures: Flip the /proc/cpuinfo appearance logic x86/CPU/AMD: Always inline amd_clear_divider() x86/mce/inject: Add missing MODULE_DESCRIPTION() line perf/x86/rapl: Switch to new Intel CPU model defines x86/boot: Switch to new Intel CPU model defines x86/cpu: Switch to new Intel CPU model defines perf/x86/intel: Switch to new Intel CPU model defines x86/virt/tdx: Switch to new Intel CPU model defines x86/PCI: Switch to new Intel CPU model defines x86/cpu/intel: Switch to new Intel CPU model defines x86/platform/intel-mid: Switch to new Intel CPU model defines x86/pconfig: Remove unused MKTME pconfig code x86/cpu: Remove useless work in detect_tme_early()
