From fe71557afbec641fee73711e40602bed37f6f33b Mon Sep 17 00:00:00 2001 From: Tang Chen Date: Wed, 24 Sep 2014 15:57:57 +0800 Subject: kvm: Add arch specific mmu notifier for page invalidation This will be used to let the guest run while the APIC access page is not pinned. Because subsequent patches will fill in the function for x86, place the (still empty) x86 implementation in the x86.c file instead of adding an inline function in kvm_host.h.
