KVM: stats: Add halt_wait_ns stats for all architectures
Add simple stats halt_wait_ns to record the time a VCPU has spent on waiting for all architectures (not just powerpc). Signed-off-by: Jing Zhang <jingzhangos@google.com> Message-Id: <20210802165633.1866976-5-jingzhangos@google.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
