[Xen-devel] [PATCH] Mask AMD CPUID masks in software before writing them to the MSRs.

[Tim Deegan <Tim.Deegan@xxxxxxxxxx>]

Mask AMD CPUID masks in software before writing them to the MSRs.
Setting bits in the CPUID mask MSR that are not set in the unmasked
CPUID response can cause those bits to be set in the masked response.
Avoid that by explicitly masking in software.
