Paul Mackerras 25fedfca94 KVM: PPC: Book3S HV: Move vcore preemption point up into kvmppc_run_vcpu ... Rather than calling cond_resched() in kvmppc_run_core() before doing the post-processing for the vcpus that we have just run (that is, calling kvmppc_handle_exit_hv(), kvmppc_set_timer(), etc.), we now do that post-processing before calling cond_resched(), and that post- processing is moved out into its own function, post_guest_process(). The reschedule point is now in kvmppc_run_vcpu() and we define a new vcore state, VCORE_PREEMPT, to indicate that that the vcore's runner task is runnable but not running. (Doing the reschedule with the vcore in VCORE_INACTIVE state would be bad because there are potentially other vcpus waiting for the runner in kvmppc_wait_for_exec() which then wouldn't get woken up.) Also, we make use of the handy cond_resched_lock() function, which unlocks and relocks vc->lock for us around the reschedule.
