With what kernel version will this be released? Or is it in some backports?

Thanx,

Ancoron

Make "acpi_backlight=video" param enable ACPI_VIDEO_BACKLIGHT_FORCE_VIDEO
as intended, instead of incorrectly enabling video output switching.

Since this is post-release and not a kitten-killer, it should probably
come directly from the stable tree. At the very least, it should be
accepted upstream (hopefully in Linus' tree, but at least in the acpi

I recently tried backporting support for the conexant codec found in
Thinkpads and it's actually not simple work. Due to many changes in
patch_conexant.c it's actually not very simple to backport changes to
support the codec in the Thinkpads, would better be apart of
alsa-backports. 

By not disabling CONFIG_THINKPAD_ACPI_ALSA in the kernel config.
	- Users with any newer or upcoming Thinkpad will not be able to
          use ALSA backports to enable use of microphone port or docking
          stations port

	- Thinkpads cannot get Ubuntu Certified.

	- If a Thinkpad user installs alsa-backports there machine is
          not as functional as thinkpad-acpi cannot load due to it
          looking for symbols from older alsa in kernel.

	- As mentioned before this adds NO functionality currently.
          Not sure why it is on. Have not heard what it adds?

Currently Thinkpads are using generic HDA support (surprisingly it works
well). But not everything needed is supported (such as microphone jack
support). Also effected is Docking station microphone jack.

More Thinkpads are coming and will need to use alsa-backports.

Can someone please consider these issues with Lucid & Lucid+1.

__gnu_mcount_nc() function is implemented in the commit
a8a48cd5add67494d96c13718cab36c465863d07 in the Lucid kernel tree,
we have to cherry pick this commit to make sure the ftrace could be
compiled and works in the fsl-mx51 branch

I cherry pick this commit and test it on my H/W, the ftrace works,
please consider to git pull this following patches from:
       git://kernel.ubuntu.com/acelan/ubuntu-lucid lp574158

Thanks,

This assumes you have linux-2.6.28 as an existing git repo.

If you do not actually want the full history, you can download a snapshot
instead with git web interface: http://kernel.ubuntu.com/git, click the
"snapshot" link besides the commit tree.

Or you may search shallow clone of git, this, though may require a more
recent git binary.
