I really really don't like it when people are fixing the wrong thing.
Why does the kernel need to get fixed when something else can't get its
CPUID dependencies straight? I don't even want to know why something
would set AVX2 without AVX?!?!
Srsly.
Some of your other bits look sensible and I'd take a deeper look but
this does not make any sense. This is a hypervisor problem - not a
kernel one.
Thx.
