BUG: sleeping function called from invalid context at kernel/locking/rtmutex.c:917
?
This issue is similar with 62c6c61("arm64: replace read_lock to rcu lock in
call_break_hook"), but comes to single_step_handler.
This also solves kgdbts boot test silent hang issue on 4.4 -rt kernel.I am going to apply this for -RT. Sebastian
