and still wait for more to start v3. Mostly, the patch #5 which
consolidates imx and mpc esdhc support will get dropped.

Hi all,
Since we didn't have any meetings last two weeks, I wanted to send out
a reminder that we are having
our regular 8am PST and 8pm PST meetings this Monday. #linaro-kernel
on freenode.
Thanks,
~Deepak
== Thomas Abraham <thomas-ab> ==
=== Highlights ===
* Listed the work items for memory regions TR for
linaro-kernel-o-general-performance blueprint.
* Submitted patches of clkdev support on Samsung platforms. This is
prerequisite for common clock and device tree support.
(http://www.mail-archive.com/linux-samsung-soc@vger.kernel.org/msg04708.html)
* Continued testing of kexec-crashdump work item on s5pv310 platform.
Could not identify the reason for kernel reboot failure. Will continue
to debug this.
=== Plans ===
* Complete testing of kexec-crashdump on s5pv310 platform.
* Submit first version of common clock support for Samsung platforms.
Hi all,
We're trying to close out on a few 11.05 items and two that stand out
are completing DT support on IGEP and u8500 boards. The code is in
place in the linaro-2.6.38 kernel but we need someone with HW to debug
why it's not working. I'm working on sorting out the u8500 testing,
but does anyone in the kernel team or landing team have the HW on hand
and able to coordinate with Grant on debugging on the IGEP?

Hi kernel folks,
there's an upstream GCC PR about banked registers not being properly
utilized in FIQ routines, specified by GCC attibutes, see here:
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48429
I was just wondering, is this GCC __attribute__(("FIQ")) feature used in
the Linux kernel as well, or are the entry paths in Linux already done
in assembler?
Thanks,
Chung-Lin
