[PATCH v11 00/28] Add gdb python scripts as kernel debugging helpers

[Jan Kiszka <jan.kiszka@siemens.com>]

Hi Andrew,

here comes the requested update of the series.

Changes since v10:
 - rebase over recent Linus master (rc6+)
 - fix stuck gdb pagination during modprobe related symbol reloading

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.

On the gdb upstream front there is good and bad news again. The good
news is that the regression reported in the last round was fixed now
[1]. The bad news is that upcoming 7.9 has a new regression that is even
causing a crash of the target kernel [2]. So the recommendation is still
to stick with gdb 7.7.

Jan
