[Xen-devel] [PATCH v1 for 4.7] x86/cpuid: fix raw FEATURESET_7d0 reporting

[Sergey Dyasli <sergey.dyasli@xxxxxxxxxx>]

Commit 62b1879693e0 ("x86: further CPUID handling adjustments") added
FEATURESET_7d0 reporting but forgot to update calculate_raw_featureset()
function. As result, the value reported by xen-cpuid contains 0.

Fix that by properly filling raw_featureset[FEATURESET_7d0].

I see that at least 4.8 also contains this bug, so other releases also
need checking.
