This series cleans up the flush_shadow_all and flush_shadow_memslot
callbacks, turning them into a single function that can be called from
kvm_arch_flush_remote_tlb. This lets MIPS use the generic TLB flushing
code in the MMU notifiers. With the upcoming refactoring of generic
MMU notifier code, without this patch MIPS would not be able to
coalesce TLB flushes anymore across multiple memslots.
Patch 1 is an unrelated cleanup that is needed for the rest to compile
(due to a call to kvm_arch_flush_remote_tlbs_memslot with a const
argument).

Paolo Bonzini (4):
KVM: constify kvm_arch_flush_remote_tlbs_memslot
KVM: MIPS: rework flush_shadow_* callbacks into one that prepares the
flush
KVM: MIPS: let generic code call prepare_flush_shadow
KVM: MIPS: defer flush to generic MMU notifier code
