Update of /cvsroot/src/sys/arch/mac68k/include
In directory netbsd1:/var/slash-tmp/cvs-serv9401

Modified Files:
        cpu.h 
Log Message:
Define single-instruction implementations of setsoft*() and siroff(),
and declare ssir as volatile.  This avoids the problem of lost softints
should a hard interrupt cause a softint to be flagged while we are
clearing a different one.

Idea from atari mtpr.h, modified/optimized by me.
