[v12,37/84] KVM: x86/mmu: Add "mmu" prefix fault-in helpers to free up generic names

Commit Message

Sean Christopherson July 26, 2024, 11:51 p.m. UTC

Prefix x86's faultin_pfn helpers with "mmu" so that the mmu-less names can
be used by common KVM for similar APIs.

No functional change intended.
