[PATCH] mem_event: fix regression affecting CR3, CR4 memory events
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 hvm.c, dropping these calls in the process.
