* Eager page splitting optimization for dirty logging, optionally
   allowing for a VM to avoid the cost of hugepage splitting in the stage-2
   fault path.
 
 * Arm FF-A proxy for pKVM, allowing a pKVM host to safely interact with
   services that live in the Secure world. pKVM intervenes on FF-A calls
   to guarantee the host doesn't misuse memory donated to the hyp or a
   pKVM guest.
 
 * Support for running the split hypervisor with VHE enabled, known as
   'hVHE' mode. This is extremely useful for testing the split
   hypervisor on VHE-only systems, and paves the way for new use cases
   that depend on having two TTBRs available at EL2.
 
 * Generalized framework for configurable ID registers from userspace.
   KVM/arm64 currently prevents arbitrary CPU feature set configuration
   from userspace, but the intent is to relax this limitation and allow
   userspace to select a feature set consistent with the CPU.
 
 * Enable the use of Branch Target Identification (FEAT_BTI) in the
   hypervisor.
 
 * Use a separate set of pointer authentication keys for the hypervisor
   when running in protected mode, as the host is untrusted at runtime.
 
 * Ensure timer IRQs are consistently released in the init failure
   paths.
 
 * Avoid trapping CTR_EL0 on systems with Enhanced Virtualization Traps
   (FEAT_EVT), as it is a register commonly read from userspace.
 
 * Erratum workaround for the upcoming AmpereOne part, which has broken
   hardware A/D state management.
