[PATCH v2 0/1] local_lock: Move this_cpu_ptr() notation from internal to main header

[Sebastian Andrzej Siewior]

While looking at what needs extra locks for PREEMPT_RT in order to rid
of the lock in local_bh_disable() I stumbled uppon two users which need
to lock the structure but the pointer is no longer per_cpu.

The moves this_cpu_ptr() from the internal header to the main one in order to
free the name space and have the __ prefix function to do the same but without
the this_cpu_ptr(). This gives us
    local_lock_nested_bh() -> on per-CPU memory
  __local_lock_nested_bh() -> on local memory.

This change has been made to all local_lock*() functions.

I made an example for the crypto user
	https://lore.kernel.org/all/20250514110750.852919-3-bigeasy@xxxxxxxxxxxxx/

and would route if via crypto once this is accepted.

v1…v2: https://lore.kernel.org/all/20250514110750.852919-1-bigeasy@xxxxxxxxxxxxx/
   - Repost without the crypto user.
