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
