Merge tag 'x86_paravirt_for_v6.4_rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull x86 paravirt updates from Borislav Petkov:
- 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
* tag 'x86_paravirt_for_v6.4_rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
x86/paravirt: Convert simple paravirt functions to asm
x86/paravirt: Merge activate_mm() and dup_mmap() callbacks
