[PATCH v3 00/13] rv: Fixes on Deterministic and Hybrid Automata

[Gabriele Monaco <gmonaco@redhat.com>]

Fix issues that were reported by bots or visible only after integration:
 * Make sure timers are always terminated and waited for when disabling
   the monitor or when the target terminates
 * Run per-cpu monitors with migration disabled since preemption is now
   enabled from tracepoints
 * Fix a wrong __user specifier in a helper function
 * Other cleanup and concurrency issues

Differences since V2 [1]:
* Applied from reviews changes to commit messages
* Rearranged order to put non-fixes and not-reviewed patches in the end
* Synchronise monitors before resetting them to avoid rearming
* Protect against racing timer callbacks during destruction

Differences since V1 [2]:
* Fix memory consistency with timer callbacks racing with resets
* Add per-obj deallocation hook in rvgen generated code
* Do not rely on clean monitor when initialising HA
* Add tracepoint synchronisation before returning per-task slots
* Fix suffix strip in dot2k
* Generate stub deallocation hooks instead of failing build when per-obj
  miss those
