+Subject: [PATCH] KVM: PPC: Avoid referencing userspace memory region in
+ memslot updates
+
+For PPC HV, get the number of pages directly from the new memslot instead
+of computing the same from the userspace memory region, and explicitly
+check for !DELETE instead of inferring the same when toggling mmio_update.
+The motivation for these changes is to avoid referencing the @mem param
+so that it can be dropped in a future commit.
+
+No functional change intended.
