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]. Signed-off-by: Sergey Dyasli <[email protected]> --- I see that at least 4.8 also contains this bug, so other releases also need checking.
