Merge tag 'x86_cpu_for_v6.5' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull x86 cpu updates from Borislav Petkov: - Compute the purposeful misalignment of zen_untrain_ret automatically and assert __x86_return_thunk's alignment so that future changes to the symbol macros do not accidentally break them. - Remove CONFIG_X86_FEATURE_NAMES Kconfig option as its existence is pointless * tag 'x86_cpu_for_v6.5' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86/retbleed: Add __x86_return_thunk alignment checks x86/cpu: Remove X86_FEATURE_NAMES x86/Kconfig: Make X86_FEATURE_NAMES non-configurable in prompt
