Yong-Xuan Wang 2121cadec4 RISCV: KVM: Introduce mp_state_lock to avoid lock inversion ... Documentation/virt/kvm/locking.rst advises that kvm->lock should be acquired outside vcpu->mutex and kvm->srcu. However, when KVM/RISC-V handling SBI_EXT_HSM_HART_START, the lock ordering is vcpu->mutex, kvm->srcu then kvm->lock. Although the lockdep checking no longer complains about this after commit f0f44752f5 ("rcu: Annotate SRCU's update-side lockdep dependencies"), it's necessary to replace kvm->lock with a new dedicated lock to ensure only one hart can execute the SBI_EXT_HSM_HART_START call for the target hart simultaneously. Additionally, this patch also rename "power_off" to "mp_state" with two possible values. The vcpu->mp_state_lock also protects the access of vcpu->mp_state.
