 1.10  06-Oct-2023  skrll Trailing whitespace
 1.9  12-Feb-2022  riastradh __cpu_simple_lock(9): Omit needless barriers in init.

It is, and always has been, the caller's responsibility to ensure the
lock is initialized before it can be used -- otherwise the memory
could hold garbage; it is nonsensical to even attempt locking
operations on it before initialization.

So there's no need to issue explicit barriers here. The barrier
seems to have been introduced in sys/arch/alpha/alpha/lock_machdep.c
rev. 1.1 (since moved to inline asm in alpha/include/lock.h) and then
copied & pasted into several other architectures.
