/*
* File: spl.h
* Author: Avadis Tevanian, Jr.
*
* Define inline macros for spl routines.
*
* HISTORY
* 21-May-91 Gregg Kellogg (gk) at NeXT
* Moved public portion to exported directory.
*
* 14-May-90 Gregg Kellogg (gk) at NeXT
* Changed SPLCLOCK from 6 to 3, as much scheduling code expects
* splclock() == splsched(). Added splusclock().
*
* 19-Jun-89 Mike DeMoney (mike) at NeXT
* Modified to allow spl assertions in spl_measured.h
