This is a patch repairing a regression in code previously functional in 4.1.x. It appears that, during some refactoring work, calls to hvm_memory_event_cr3 and hvm_memory_event_cr4 were lost. These functions were originally called in mov_to_cr() of vmx.c, but the commit http://xenbits.xen.org/hg/xen-unstable.hg/rev/1276926e3795 abstracted the original code into generic functions up a level in

The patch ''mem_event: use wait queue when ring is full'' I just sent out makes use of the waitqueue feature.

But for some reason the vcpu does not make progress after the first wakeup. In my debugging there is one
