If anyone has any objections, please let me know. ------------------ From: Adrian Hunter [ Upstream commit 695fc4510615f8db40ebaf7a2c011f0a594b5f77 ] Use the change of NR to detect whether an asynchronous branch is a VM-Exit. Note VM-Entry is determined from the vmlaunch or vmresume instruction, in which case, sample flags will show "VMentry" even if the VM-Entry fails.
