Hi,

Intel has released new version of Intel Architecture Instruction Set
Extensions Programming Reference, add new features like AVX-512, MPX, etc.

Patch 1/5 fix a bug of current Xen xsave;
Patch 2/5 adds definiation of these new instruction set extension. 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;

It would help if the patches were linked to the covering thread.

I'm sorry, you sent this two days ago. 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...

Oh, it's me who should be sorry (in fact you always feedback _very_ fast).
I just want MPX feature catch up with 4.4 so ping for it some fast :)
Now I know 4.4 code freezen so I revoke my ping.
