This is a patch repairing a regression in code previously functional in 4.1.x. It appears that, during some refactoring work, call to hvm_memory_event_cr0 was lost. This function was 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 the call in the process. The same issue affected the CR3 and CR4 events, which were fixed in patch http://xenbits.xensource.com/hg/xen-unstable.hg/rev/7ab899e46347.
