Paolo Bonzini 76671054f9 KVM/arm64 changes for 7.3
- Add support for 'slot' based PMU events, paired with new UAPI that
    compels the user to select a specific PMU implementation
 
  - Lazy save/restore of vCPU state for pKVM, along with various fixes
    and cleanups to the management of vCPU state between the untrusted
    host and pKVM hypervisor
 
  - Disable traps of EL1 registers for nested hypervisors when FEAT_NV2p1
    is present, guaranteeing that EL2-specific register bits are stateful
    in the EL1 counterpart
 
  - Leverage FEAT_NV3 to avoid unnecessary ERET/TLBI traps when the scope
    of those instructions remains 'in host' (i.e. L1 kernel/userspace)
 
  - Pile of fixes for the management of the VNCR pseudo-TLB, such as
    under-invalidations and races with concurrent TLBIs on other vCPUs
 
  - Consolidate the non-protected and pKVM view of ICH_VTR_EL2 to a
    runtime-patched constant, allowing the same data to be shared with
    pKVM prior to dropping host privileges
 
  - Considerable pile of LLM-assisted fixes around the shop but mostly in
    the VGIC, our in-kernel generator of bugs (and sometimes interrupts)
