Bug description:
[Impact]
When PCIDs are enabled on Alder Lake and Raptor Lake, INVLPG will not flush
the global TLB entries. This can lead to info leak or undefined behavior.
[Mitigation]
Boot with nopcid on affected systems.
[Test case]
There is no particular test case.
[Potential regressions]
This affects performance on the affected systems. TLB behavior could also be
affected.
