Merge tag 'x86_asm_for_v5.19_rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull x86 asm updates from Borislav Petkov:
- A bunch of changes towards streamlining low level asm helpers'
calling conventions so that former can be converted to C eventually
- Simplify PUSH_AND_CLEAR_REGS so that it can be used at the system
call entry paths instead of having opencoded, slightly different
variants of it everywhere
- Misc other fixes
