Subject: [PATCH 0/4] gdb script for kconfig and timer list

This is a handful of changes to the kernel's gdb scripts to do some more
debugging with kgdb. The first patch allows the vmlinux to be reloaded
from where it was specified on the command line so that this set of
scripts can be used from anywhere. The second patch adds a script to
dump the config.gz to a file on the host debugging machine. The third
patch adds some rb tree utilities and the last patch uses those rb tree
walking utilities to dump out the contents of /proc/timer_list from a
system under debug.

I'm guessing that Andrew will pick these patches up. I don't know who
maintains these gdb scripts but it looks like Andrew has been doing the
lifting recently.
