Subject: [PATCH v6 00/21] Add gdb python scripts as kernel debugging helpers

It's been a while since my last update of these patches. This one is
mostly about cleaning up and making some details more convenient:
 - proper registration of module data segments to access module
   variables - this obsoletes lx_modvar again
 - stable breakpoint target on do_init_module in order to track module
   loading more reliably from the debugger
 - internal refactoring with the aim to "pythonize" the scripts (credits
   for all valuable suggestions belong to Tatiana, many thanks, for
   improper implementations to me)

See http://lkml.indiana.edu/hypermail/linux/kernel/1210.0/01598.html for
the original description and

    git://git.kiszka.org/linux.git queues/gdb-scripts

for the latest version.
