Paolo Bonzini 45b890f768 KVM/arm64 updates for 6.7
- Generalized infrastructure for 'writable' ID registers, effectively
    allowing userspace to opt-out of certain vCPU features for its guest
 
  - Optimization for vSGI injection, opportunistically compressing MPIDR
    to vCPU mapping into a table
 
  - Improvements to KVM's PMU emulation, allowing userspace to select
    the number of PMCs available to a VM
 
  - Guest support for memory operation instructions (FEAT_MOPS)
 
  - Cleanups to handling feature flags in KVM_ARM_VCPU_INIT, squashing
    bugs and getting rid of useless code
 
  - Changes to the way the SMCCC filter is constructed, avoiding wasted
    memory allocations when not in use
 
  - Load the stage-2 MMU context at vcpu_load() for VHE systems, reducing
    the overhead of errata mitigations
 
  - Miscellaneous kernel and selftest fixes
