[PATCH v10 00/27] Add gdb python scripts as kernel debugging helpers

[Jan Kiszka]

Hi Thomas,

as discussed earlier today, I'm sending out a fresh rebase of the gdb
scripts so that you can organize the next steps towards merge. Thanks
for this in advance!

Changes since v9:
 - rebase over recent Linux version
 - use a generator instead of iterator for task list,
   fixes thread-group iteration [Daniel Wagner]
 - apply generator scheme on other iterations
 - propose myself as maintainer

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.

There is still some issue with gdb >= 7.8 when parsing symbols of kernel
modules, because I didn't deliver those folks the requested core dump of
gdb so far - done now. So up to version 7.7 remains recommended for the
time being.

Jan
