+### Added
+ - On x86, support for features new in Intel Sapphire Rapids CPUs:
+ - PKS (Protection Key Supervisor) available to HVM/PVH guests.
+ - VM-Notify used by Xen to mitigate certain micro-architectural pipeline
+ livelocks, instead of crashing the entire server.
+ - Bus-lock detection, used by Xen to mitigate (by rate-limiting) the system
+ wide impact of a guest misusing atomic instructions.
