I could look at
* ftrace
* kprobes
* VFP/NEON coredump support
* Thumb2 kernel benchmarking (not included in the original blueprints)
In the meantime, I'll continue pushing the OMAP Thumb2 kernel stuff,
but the real work is complete.
I've had a brief look at the coredump stuff, but I'm not committed yet.
I'm keen to hear people's views on which task sounds the most useful.
Cheers

Hello!
Just a reminder, we are going to be using IRC rather than phone for
today's linaro-kernel meetings.
Let's use #linaro-kernel on Freenode for today's linaro-kernel meetings.
Thanx, Paul
=== Device Tree ===
* Studying clkdev.c and trying to come up with the approach to
match clock node with struct clk pointer
* Reviewed and tested the basically mx51 dt patch set posted by
Jason
=== Misc ===
* Sent out mxs dma and mmc patch v3, and hopefully this version
could get merged

Regards,
Shawn
== U-Boot Cache Maintenance ==
* Working on v2 series - fixing review comments
== U-Boot SPL ==
* Sent an early drop to John Rigby.
* Added DMM initialization
* Added mux support and corrected mux values
* Testing with different versions of OMAP4 board
== Device Tree ==
* Modified s5pv310 device tree support as per comments from Grant for
the v2 patchset.
* Working on device tree based probe for uart driver, console init
from dt took up lot of time.
* Planning to submit v3 s5pv310 device tree patchset this week.
* sdhci driver will be modified next for device tree based probe.
== Storage performance eMMC ==
* Got trim to work on my mmci host driver
* Rebasing async mmc requests on top of 2.6.38-rc4 mmci (testing is not done).
* Started adding tests in mmc_test.c in kernel to investigate trim,
bg and mmc async requests.
* mmc_test results so far: Write after TRIM show 10 % max increase
for linear writes on my particular eMMC.
== Kernel work ==
* Reviewed TI pruss drivers
* Reviewed new unicore patches
== Flash drive performance ==
* Completed lwn.net article
* Many discussions based on this work
== Noteworthy ==
* Article now online: http://lwn.net/Articles/428584/
* Got invited to do the keynote at ELC
== RCU priority boosting ==
* Between fixing some Power bugs and finding an 8-CPU system that avoids others, testing of RCU priority boosting has restarted.
== Processes ==
* Completed a couple of TSC license requests.
* Started one more TSC license request.
== Misc ==
* Continuing chasing additional Power bugs to enable tests on larger systems.

=== Activity ===
==== hardware-n-kernel-standard-architecture ====
* Upstream link-time discard versus SMP_ON_UP problem still
not fixed. Russell suggested a patch; currently trying to
confirm whether it got merged anywhere.
* omap3/4 Thumb-2 compatiblity patches re-posted (again). By
reverting the low-level PM functionality to ARM for correct
interoperation with firmware, positive PM test results have
now been seen on omap3.
* Spent a bit of time trying to understand coredump generation
on ARM.
==== miscellaneous ====
* Cambridge validation lab support:
* Tried to rescue the new, broken vexpress board. No
success yet, but I now have a firmware upgrade which I
think should fix the problem.
* Tried to set up u8500 boards, but failed due to a lack of
serial breakout boards.
==== Plans ====
* Discuss prioritisation for outstanding kernel tasks.
* Write up the output from the Freescale i.MX BSP review
discussion, and post for comment.
==== Absences ====
* Possible absense of a couple of days in early March
(unconfirmed).
