[PATCH v2 0/4] KVM: arm64: Use 'generic' vCPU target across all uarches

[Oliver Upton <oliver.upton@linux.dev>]

kvm_vcpu_init::target is quite useless at this point. We don't do any
uarch-specific emulation in the first place, and require userspace
select the 'generic' vCPU target on all but a few implementations.

Small series to (1) clean up usage of the target value in the kernel and
(2) switch to the 'generic' target on implementations that previously
had their own target values. The implementation-specific values are
still tolerated, though, to avoid UAPI breakage.

v1: https://lore.kernel.org/kvmarm/20230623194258.2648987-1-oliver.upton@linux.dev/

v1 -> v2:
 - Set the generic v8 target in the kvm_vcpu_init struct initializer
   (Marc)
 - Use the kvm_vcpu_initialized() helper (Zenghui)
 - Collect Zenghui's ack/reviews (Thanks!)

Oliver Upton (4):
  KVM: arm64: Delete pointless switch statement in kvm_reset_vcpu()
  KVM: arm64: Remove pointless check for changed init target
  KVM: arm64: Replace vCPU target with a configuration flag
  KVM: arm64: Always return generic v8 as the preferred target
