From e59dbe09f8e6fb8f6ee19dc79d1a2f14299e4cd2 Mon Sep 17 00:00:00 2001 From: Takuya Yoshikawa Date: Thu, 4 Jul 2013 13:40:29 +0900 Subject: KVM: Introduce kvm_arch_memslots_updated() This is called right after the memslots is updated, i.e. when the result of update_memslots() gets installed in install_new_memslots(). Since the memslots needs to be updated twice when we delete or move a memslot, kvm_arch_commit_memory_region() does not correspond to this exactly. In the following patch, x86 will use this new API to check if the mmio generation has reached its maximum value, in which case mmio sptes need to be flushed out.
