Subject: Another fix for xmon on non-standard MMU machines
Date: Mon, 10 Sep 2001 19:47:30 +1000 [thread overview]
Message-ID: <20010910194730.J4823@zax> (raw)
This patch stops xmon from attempting to print the segment registers
on machines where CONFIG_PPC_STD_MMU is not set. This prevents xmon
from causing an exception when the 'S' command is used on the 4xx (and
others).
