Subject: KVM: x86/mmu: Move definition of make_mmu_pages_available() up
X-Git-Tag: v5.6-rc1~106^2~148
X-Git-Url: https://asedeno.scripts.mit.edu/gitweb/?a=commitdiff_plain;h=ba7888dde6afc32885a0960f11b898ff97d4a060;p=linux.git

KVM: x86/mmu: Move definition of make_mmu_pages_available() up

Move make_mmu_pages_available() above its first user to put it closer
to related code and eliminate a forward declaration.

No functional change intended.
