Subject: [PATCH v2 0/5] 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.

Andrew picked these patches up into -mm. I'm resending for full review
instead of just sending the diff.

Changes from v1:
 * Fixed config dumping script off-by-one error on builtin config size
 * Silenced pep8 style warnings and errors
 * Added a new patch at the end to fix existing warnings
 * Fixed some TODOs in timerlist printing
  * cpumask printing
  * jiffies printing uses jiffies_64 now to avoid conversion problems
