The original fix disabled the xsaves feature for zen1/2. The issue has
since been fixed in the cpus microcode and this patch keeps the feature enabled
if the microcode version is recent enough to contain the fix.
The patch had to be altered slightly to apply cleanly on 6.5, but no
changes content-wise.
