All dumping functions invoked by the "runq" keyhandler are called with

Hello,
The main aim of this series is to reduce the pressure around
cpu_add_remove_lock by converting it into a rw lock. Most users of the
lock want to take it in read mode, as they only care about the maps not
changing.
Patch #2 makes the writers take the lock in blocking mode, this is
mainly
Most users of the cpu maps just care about the maps not changing while
the lock is being held, but don't actually modify the maps.
Convert the lock into a rw lock, and take the lock in read mode in
get_cpu_maps and in write mode in cpu_hotplug_begin. This will lower
the contention around the
Don't allow cpu_hotplug_begin to fail by converting the trylock into a
blocking lock acquisition. Write users of the cpu_add_remove_lock are
limited to CPU plug/unplug operations, and cannot deadlock between
themselves or other users taking the lock in read mode as
cpu_add_remove_lock is always
