--------------------------------

commit 22da5a07 upstream.

Principally, in order to get rid of #define RET in this code to make
place for a new RET, but also to clarify the code, rename a bunch of
things:

  s/UNLOCK/IRQ_RESTORE/
  s/LOCK/IRQ_SAVE/
  s/BEGIN/BEGIN_IRQ_SAVE/
  s/\<RET\>/RET_IRQ_RESTORE/
  s/RET_ENDP/\tRET_IRQ_RESTORE\rENDP/

which then leaves RET unused so it can be removed.
