Update of /cvsroot/src/sys/arch/hp300/hp300
In directory netbsd1:/var/slash-tmp/cvs-serv29668

Added Files:
	db_memrw.c 
Log Message:
Add a db_memrw.c that understands how to write to read-only kernel text
(remaps page read/write/cache-inhibit, does write, restores previous
mapping).  Kernel text no longer needs to be read/write with DDB/KGDB
is in the kernel.

Based on a similar module written for the Sun3 port by Gordon Ross,
and modified somewhat by me.
