KVM: PPC: RCU'ify the Book3s MMU
So far we've been running all code without locking of any sort. This wasn't really an issue because I didn't see any parallel access to the shadow MMU code coming. But then I started to implement dirty bitmapping to MOL which has the video code in its own thread, so suddenly we had the dirty bitmap code run in parallel to the shadow mmu code. And with that came trouble. So I went ahead and made the MMU modifying functions as parallelizable as I could think of. I hope I didn't screw up too much RCU logic :-). If you know your way around RCU and locking and what needs to be done when, please take a look at this patch. Signed-off-by: Alexander Graf <agraf@suse.de> Signed-off-by: Avi Kivity <avi@redhat.com>
