Update of /cvsroot/src/sys/arch/sparc/sparc
In directory netbsd1:/var/slash-tmp/cvs-serv28346

Modified Files:
        locore.s 
Log Message:
1. Implement a trick from Chris Torek: if an unhandled interrupt occurs
   during auto-configuration (`cold'), raise interrupt level to splhigh
   and return, instead of reporting a stray interrupt.

2. In cpu_switch(), start running a newly selected proces at splclock()
   instead of the saved IPL, allowing high-priority interrupts in
   ctx_alloc() which can take many cycles to install a new context
   (especially on the two-level sun4c MMU).
