Merge branch 'kvm-arm64/doublefault2' into kvmarm/next

* kvm-arm64/doublefault2: (33 commits)
  : NV Support for FEAT_RAS + DoubleFault2
  :
  : Delegate the vSError context to the guest hypervisor when in a nested
  : state, including registers related to ESR propagation. Additionally,
  : catch up KVM's external abort infrastructure to the architecture,
  : implementing the effects of FEAT_DoubleFault2.
  :
  : This has some impact on non-nested guests, as SErrors deemed unmasked at
  : the time they're made pending are now immediately injected with an
  : emulated exception entry rather than using the VSE bit.
  KVM: arm64: Make RAS registers UNDEF when RAS isn't advertised
  KVM: arm64: Filter out HCR_EL2 bits when running in hypervisor context
  KVM: arm64: Check for SYSREGS_ON_CPU before accessing the CPU state
  KVM: arm64: Commit exceptions from KVM_SET_VCPU_EVENTS immediately
  KVM: arm64: selftests: Test ESR propagation for vSError injection
  KVM: arm64: Populate ESR_ELx.EC for emulated SError injection
  KVM: arm64: selftests: Catch up set_id_regs with the kernel
  KVM: arm64: selftests: Add SCTLR2_EL1 to get-reg-list
  KVM: arm64: selftests: Test SEAs are taken to SError vector when EASE=1
  KVM: arm64: selftests: Add basic SError injection test
  KVM: arm64: Don't retire MMIO instruction w/ pending (emulated) SError
  KVM: arm64: Advertise support for FEAT_DoubleFault2
  KVM: arm64: Advertise support for FEAT_SCTLR2
  KVM: arm64: nv: Enable vSErrors when HCRX_EL2.TMEA is set
  KVM: arm64: nv: Honor SError routing effects of SCTLR2_ELx.NMEA
  KVM: arm64: nv: Take "masked" aborts to EL2 when HCRX_EL2.TMEA is set
  KVM: arm64: Route SEAs to the SError vector when EASE is set
  KVM: arm64: nv: Ensure Address size faults affect correct ESR
  KVM: arm64: Factor out helper for selecting exception target EL
