Merge tag 'x86-cleanups-2024-01-08' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip

Pull x86 cleanups from Ingo Molnar:

 - Change global variables to local

 - Add missing kernel-doc function parameter descriptions

 - Remove unused parameter from a macro

 - Remove obsolete Kconfig entry

 - Fix comments

 - Fix typos, mostly scripted, manually reviewed

and a micro-optimization got misplaced as a cleanup:

 - Micro-optimize the asm code in secondary_startup_64_no_verify()
