[PATCH 0/5] KVM: arm64: Reorganise vcpu first run

KVM/arm64 relies heavily on a bunch of things to be done on the first
run of the vcpu. We also do a bunch of things on PID change. It turns
out that these two things are pretty similar (the first PID change is
also the first run).

This small series aims at simplifying all that, and to get rid of the
vcpu->arch.has_run_once state.

Marc Zyngier (5):
  KVM: arm64: Move SVE state mapping at HYP to finalize-time
  KVM: arm64: Move kvm_arch_vcpu_run_pid_change() out of line
  KVM: arm64: Merge kvm_arch_vcpu_run_pid_change() and
    kvm_vcpu_first_run_init()
  KVM: arm64: Restructure the point where has_run_once is advertised
  KVM: arm64: Drop vcpu->arch.has_run_once for vcpu->pid
