[ACTIVITY] (Anton Vorontsov) 2012-05-21 - 2012-06-01

by Anton Vorontsov

== Highlights == * Sent v5 of pstore/console patch set, so far it didn't receive any objections. Perhaps need to ping Greg, as the merge window is now closed; * Finished and sent out pstore/ftrace support; it got a preliminary thumbs up from Steven. Will need to merge the support to the generic function tracer, turning persistent storage into a flag. * Discussed various approaches to make continuous console logging in pstore. And as a part of it tried to make linux_banner printing somewhat more consistent. But folks did not like it, so in the end we'll have just one console log buffer, as it was with ram_console; * Restarted work on vmevents, but got unflattering comments from KOSAKI, plus Minchan started to doubt about the notifiers in general. There is some blowing hot and cold started again. == Plans == * Repost pstore/ftrace support with Steven Rostedt comments fixed. * Move pstore registration earlier, so that we can record early oopses. Suggested by Colin Cross. * Make pstore ecc settings configurable, i.e. address Arve Hjønnevåg's "nice to have" comment on pstore; * I plan to finish all the major pstore items this week, and thus will have to pick a new task; * See how vmevents discussion turns out. -- Anton Vorontsov Email: cbouatmailru(a)gmail.com

omap2plus kernel CI hwpacks fails to boot

by Deepti Kalakeri

Hello, Its been close to a month now that the kernel CI hwpacks built on ci.linaro.org with default omap2plus defconfigs (available in the linux-arm-soc, linux-next, linux-linaro, linux) are failing to boot on the boards. Here is an example hwpack built using the linux-linaro tree with omap2plus defconfig on ci.linaro.org which is failing to boot, in case you want to try to test it. http://snapshots.linaro.org/kernel-h wpack/linux-linaro-tracking/linux-linaro-tracking_panda-omap2plus/hwpack_linaro-lt-panda_20120509-0641_b64_armel_supported.tar.gz<http://snapshots.linaro.org/kernel-hwpack/linux-linaro-tracking/linux-linar…> I was able to fix the above boot problem of the CI kernel hwpacks built with omap2plus defconfig by adding the options similar to the ones available in (linux-linaro tree) default omap4 defconfig on top of the default omap2plus defconfig options. Here is the list of the config options which I added http://paste.ubuntu.com/977642/ along with the omap2plus defconfig to make it work. Can someone help me with the basic omap2plus defconfig options that will be required to boot the hwpack on the board. Does anyone care of kernel builds for linux-arm-soc, linux-next, linux-linaro, linux tree using omap2plus defconfigs ? Apart from this, there are build failures with the linux-next trees failing since last 20 days. https://ci.linaro.org/jenkins/view/Linux%20%28next%29/ lists such failing build jobs. For example the following job fails https://ci.linaro.org/jenkins/view/Linux%20%28next%29/job/linux-next_panda-… . Can someone look at these linux-next build failures ? -- Thanks and Regards, Deepti Infrastructure Team Member, Linaro Platform Teams Linaro.org | Open source software for ARM SoCs Follow Linaro: http://www.facebook.com/pages/Linaro http://twitter.com/#!/linaroorg - http://www.linaro.org/linaro-blog

[PATCH v3 0/9] Fixes for common mistakes w/ for_each_process and task->mm

by Anton Vorontsov

Hi all, This is another resend of several task->mm fixes, the bugs I found during LMK code audit. Architectures were traverse the tasklist in an unsafe manner, plus there are a few cases of unsafe access to task->mm in general. There were no objections on the previous resend, and the final words were somewhere along "the patches are fine" line. In v3: - Dropped a controversal 'Make find_lock_task_mm() sparse-aware' patch; - Reword arm and sh commit messages, per Oleg Nesterov's suggestions; - Added an optimization trick in clear_tasks_mm_cpumask(): take only the rcu read lock, no need for the whole tasklist_lock. Suggested by Peter Zijlstra. In v2: - introduced a small helper in cpu.c: most arches duplicate the same [buggy] code snippet, so it's better to fix it and move the logic into a common function.
