[PATCH v2 0/2] x86/spec: misc fixes for XSA-456

Posted by Roger Pau Monne 1 week, 6 days ago

Hello,

Fix patch fixing the printing of whether BHB-entry is used for PV or
HVM, second patch refines a bit the logic to decide whether the lfence
on entry can be elided for the entry points.

Thanks, Roger.
