Revert the FLUSH_L1D enabling, which has multiple fatal bugs, clean up
the existing PRED_CMD handling, and reintroduce FLUSH_L1D virtualization
without inheriting the mistakes made by PRED_CMD.
The last patch hardens SVM against one of the bugs introduced in the
FLUSH_L1D enabling.
I'll post KUT patches tomorrow. I have the tests written (and they found
bugs in my code, :shocked-pikachu:), just need to write the changelogs.
Wanted to get this out sooner than later as I'm guessing I'm not the only
one whose VMs won't boot on Intel CPUs...
