Subject: [PATCH 05/14] KVM: monolithic: add more section prefixes in the KVM common code

Add more section prefixes of some KVM common code function because
with the monolithic KVM model the section checker can now do a more
accurate static analysis at build time and this allows to build
without CONFIG_SECTION_MISMATCH_WARN_ONLY=n.
