CVS commit: src/sys/arch/powerpc

[Tim Rightnour <garbled%netbsd.org@localhost>]

Module Name:    src
Committed By:   garbled
Date:           Thu Feb  7 03:20:17 UTC 2008

Modified Files:
        src/sys/arch/powerpc/oea: oea_machdep.c
        src/sys/arch/powerpc/powerpc: bus_space.c trap_subr.S

Log Message:
Code to disable BAT use on cpu's that either don't have BAT's, or don't
gain any benefit from them.  This nets a small speedup on the POWER3, and
is probably needed for POWER5, which might not emulate BATs like the 3 does.
Also, thanks to Matt Thomas, who suggested re-using alitrap rather than
writing a new dsinobattrap that would have looked remarkably identical
when finished.
