This is the third revision of this series that tries to address the problem of synchronising with a remote processor with as much flexibility as possible. Two things to pay attention to: 1) Function rproc_actuate() has been abandoned to avoid creating another way to start a remote processor from a kernel driver. Arnaud expressed the opinion that it is semantically questionnable to synchronise with a remote processor when calling rproc_boot(). We could rename rproc_boot() to rproc_actuate() but I'll wait to see what other people think before doing so. 2) The allocation of the synchronisation states has been split from the remote processor allocation. A new function rproc_set_state_machine() does all the work now. Proceeding this way has made the patchset a lot more simple. Other than the above I have tried to address all the comments made on the second revision. If a comment was not addressed it simply fell through the cracks rather than ignored. In such a case please reiterate your point of view and I'll be sure to address it. Applies cleanly on rproc-next (305ac5a766b1).
