The first patch ensures that XSAVES is not exposed in the guest until we emulate MSR_IA32_XSS. The second exports XSAVE data in the correct format.
I tested these on a non-XSAVES system so they should not be completely broken, but I need some help. I am not even sure which XSAVE states are _not_ enabled, and thus compacted, in Linux.
Note that these patches do not add support for XSAVES in the guest yet, since MSR_IA32_XSS is not emulated.
If they fix the bug Nadav reported, I'll add Reported-by and commit.
Thanks,
Paolo
