Dylan Reid b04926680c linux: Switch from a run mutex to a channel ... Using a channel will allow for more complicated messages to be sent to the vcpu thread. Adding debug support will require being able to process each message from the main thread. The atomic state worked well when every CPU needed a message and when transient state changes can be dropped. Neither of those assumptions will hold true when using this communication channel for debugging message such as setting and getting vcpu registers or single stepping a particular cpu. The run state is now per-cpu so that individual CPUs can be stopped and stepped by GDB in later commits.
