Subject: [PATCH 0/2] KVM: RISC-V: MMU bug fix and cleanup

Bug fix and a cleanup for things I noticed by inspection when working on
the scalable memslots series.  Regarding the fix, unless there's a magic
unmapping hiding in the corners of the MMU, RISC-V completely fails to
handle memslot DELETE or MOVE.

Compile tested only.

  KVM: RISC-V: Unmap stage2 mapping when deleting/moving a memslot
  KVM: RISC-V: Use common KVM implementation of MMU memory caches
