  x86/paravirt: Convert simple paravirt functions to asm (2023-03-17 13:29:47 +0100)

----------------------------------------------------------------
- Convert a couple of paravirt callbacks to asm to prevent
  -fzero-call-used-regs builds from zeroing live registers because
  paravirt hides the CALLs from the compiler so latter doesn't know
  there's a CALL in the first place

- Merge two paravirt callbacks into one, as their functionality is
  identical
