KVM: arm/arm64: timer: remove request-less vcpu kick
The timer work is only scheduled for a VCPU when that VCPU is blocked. This means we only need to wake it up, not kick (IPI) it. While calling kvm_vcpu_kick() would just do the wake up, and not kick, anyway, let's change this to avoid request-less vcpu kicks, as they're generally not a good idea (see "Request-less VCPU Kicks" in Documentation/virtual/kvm/vcpu-requests.rst) Signed-off-by: Andrew Jones <drjones@redhat.com> Reviewed-by: Christoffer Dall <cdall@linaro.org> Signed-off-by: Christoffer Dall <cdall@linaro.org>
