Hi all,
I want to give everyone a heads up about the kernel.org outage. As
most of you know, kernel.org was compromised by an outside hacker and
has been taken down for rebuild. You can find the coverage on
lwn.net[1][2][3].
[1] http://lwn.net/Articles/457142/ - Initial notice
[2] http://lwn.net/Articles/458809/ - Further details
[3] http://lwn.net/Articles/460376/ - An update from H. Peter Alvin
Because kernel.org is central to the kernel development process,
particularly since the majority of git trees pulled by Linus live
there, the security of kernel.org is of paramount importance. It is
critically important that when the kernel.org infrastructure comes
back up that it not be vulnerable to another attack, so as part of
rebuilding the infrastructure, all of the policies around how
developers access kernel.org as well as how Linus pulls maintainer
trees is under review.
The reason for this email is to give you a heads up about what you
should expect when kernel.org becomes live again. There is a strong
likelyhood that maintainers will need to start GPG signing branches
that they will ask Linus to pull. Nothing has been decided firmly
(indeed, we won't know until Linus himself makes a decision about what
he will accept), and it will definitely be a topic for the upcoming
Kernel Summit at the end of October. However, it is worth taking the
opportunity now to get familiar with GPG and to create a key for
yourself. The Debian developers among you will already be familiar
with this process, /even if you don't have a kernel.org account/. The
Debian keysigning page[4] is a good place to start reading.

I'll post more details as I learn them. In the mean time, you can
email me if you have any questions and I'll do my best to answer them.

== Rajendra Nayak <rnayak> ==
== Highlights ==
* Reworked regulator dt support patches based on comments
from Mark/Grant. Waiting for a repost of the dependent i2c-twl
support series to resend it out for review.
* Started omap mmc driver dt migration. Will use auxdata to start
with for all the function pointers currently passed from pdata
* Study/review the pinmux/pinctrl series from Linusw.
== Plans ==
* Repost regulator dt support once i2c-twl series is out
* Post omap mmc dt patches, using regulator mappings from dt
* Use pinmux/pinctrl framework for OMAP
=== Highlights ===
* Sent out prototype of sched flag based alternative to suspend-blockers
to lkml for discussion. Got mostly negative feedback, but not as much
as I was expecting.
* Merged a number of fixes and changes to the config fragment
merge_config.sh script from the community.
* Provided some android roadmap details for Deepak.
* Reviewed & tested some posix timer patches from tglx
* Started researching timer freezing approaches to power saving.
=== Plans ===
* Work on prototyping a sched flag based timer freezing to allow
de-prioritizing unimportant timers and allow for longer periods in deep
idle states. This is similar to the suspend-blockers alternative idea,
but just showing what we could do with such a scheduler state.
* Resubmit merge_config.sh script to lkml
* Follow up on potential ashmem functionality patch by Dave Hansen.
* Try to catch up on blueprint items Mounir has been pushing for that
I've been forgetting to do (Sorry, Mounir!).
=== Issues ===
* Not getting much response on Linaro Connect expense issue yet.
* I've been heads down on the suspend-blocker idea for a bit, so I'm
probably forgetting other things I should be doing, so if I've not
responded to some mail or haven't acted on something I should have,
please ping me and remind me. Apologies!
== Dave Martin <dmart> ==
=== Activity Summary ===
* Spent a lot of time doing and discussion image testing.
* Some discussions around testing/quality/documentation
* Posted RFC for enabling autoloading of AMBA peripheral driver modules.
* Integrated some people's feedback in the Versatile Express DT
patches. Additonal work + repost is still needed.
* Thumb-2 kernel migration advice stalled due to activities around
validation this week.
=== Plans ===
* (Really) complete and post advice for Thumb-2 kernel migration.
Prompt for further feedback on minor Thumb-2 randconfig issues:
* v6/v7 single kernel Thumb-2 undef fixup patches: currently waiting
for Russell/Arnd to comment
* Fixing some Thumb-2 related randconfig errors reported by Arnd:
* pxa/pj4/iwmmxt uses non-Thumb-2-compatible code: waiting for
feedback (probably needs a Marvell expert to comment)
* tegra2 uses non-Thumb-2-compatible code: waiting for feedback from
Colin Cross.
=== Work Items ===

my sanity

linux-next for maturing

* Watch the DBx500 PRCMU drivers update, pushed
Sam again today
* Get into struct clk generalization and movement of clk
drivers into drivers/clk

the system. (Or is Niklas doing this?)
=== Issues ===
* Appended device trees does not work for us.
Still don't know why.
* Shanghaiied for internal advisory at ST-Ericsson for
too much time last week, ~30%
Thanks,
