From f032b73459eed4897bcafee2b1d37a817f1bb596 Mon Sep 17 00:00:00 2001 From: Bharata B Rao Date: Wed, 12 Dec 2018 15:15:30 +1100 Subject: [PATCH] KVM: PPC: Pass change type down to memslot commit function Currently, kvm_arch_commit_memory_region() gets called with a parameter indicating what type of change is being made to the memslot, but it doesn't pass it down to the platform-specific memslot commit functions. This adds the `change' parameter to the lower-level functions so that they can use it in future.
