It also adjusts valid xcr0 checking; Patch 3/5 handle MPX IA32_BNDCFGS msr; Patch 4/5 expose MPX feature to HVM guest; Patch 5/5 enable MPX feature to HVM guest; Thanks, Jinsong

How fast a response do you expect (even more so that quite likely only the first patch would be acceptable now that we''re in code freeze mode)? If there was no response after a week, or if you were fixing a critical bug, I''d understand you pinging...
