### 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.
- - xl/libxl can customize SMBIOS strings for HVM guests.
- - Add support for AVX512-FP16 on x86.
- - On Arm, Xen supports guests running SVE/SVE2 instructions. (Tech Preview)
- - On Arm, add suport for Firmware Framework for Arm A-profile (FF-A) Mediator
- (Tech Preview)
- - Add Intel Hardware P-States (HWP) cpufreq driver.
- - On Arm, experimental support for dynamic addition/removal of Xen device tree
- nodes using a device tree overlay binary (.dtbo).

- Introduce two new hypercalls to map the vCPU runstate and time areas by
physical rather than linear/virtual addresses.
- - On x86, support for enforcing system-wide operation in Data Operand
- Independent Timing Mode.
- The project has now officially adopted 6 directives and 65 rules of MISRA-C.
### Removed
Collect all x86 and ARM changes together instead of having them scattered. Tweak grammar as necessary. No change.
