Merge tag 'x86_mm_for_v5.17_rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull x86 mm updates from Borislav Petkov:
- Flush *all* mappings from the TLB after switching to the trampoline
pagetable to prevent any stale entries' presence
- Flush global mappings from the TLB, in addition to the CR3-write,
after switching off of the trampoline_pgd during boot to clear the
identity mappings
- Prevent instrumentation issues resulting from the above changes
