Re: gdb on IBM Walnut board panics the kernel

I'm running Monta Vista's Hard Hat Linux (11/26/200 2.4.0-test2) on an
IBM 405GP walnut rev D board. On an x86 PC running Red Hat Linux 7.0,
using MV's CDK, I built a small program using ppc_4xx-gcc with the -g
switch.

Attached is a patch to files in linux/arch/ppc/kernel and
include/asm-ppc that makes the kernel work fine with debugging user mode
programs with a stock gdb 5.0. (we had problems with gdb 4.18, but a
cross compiled gdb5 worked fine).

cd linux; patch -p0 < diffs

Don't know how it compares with monta vista's fixes, but we've been
running these in our development systems for over a month.  We also have
patches that makes PCI device configuration work better in the absence
of a real bios on the walnut board, if anyone would like them.
