Merge tag 'x86_alternatives_for_v6.5' of git://git./linux/kernel/git/tip/tip

Pull x86 instruction alternatives updates from Borislav Petkov:

 - Up until now the Fast Short Rep Mov optimizations implied the
   presence of the ERMS CPUID flag. AMD decoupled them with a BIOS
   setting so decouple that dependency in the kernel code too

 - Teach the alternatives machinery to handle relocations

 - Make debug_alternative accept flags in order to see only that set of
   patching done one is interested in

 - Other fixes, cleanups and optimizations to the patching code
