Paolo Bonzini cc744042d9 KVM/arm64 updates for 6.5
- Eager page splitting optimization for dirty logging, optionally
    allowing for a VM to avoid the cost of block 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.
 
 As a consequence of the hVHE series reworking the arm64 software
 features framework, the for-next/module-alloc branch from the arm64 tree
 comes along for the ride.
