Patchwork [RFC,v3,0/9] Linux 3.0 build support

v3: - task-base.bb: fix a problem that *pcmia26 couldn't be found.

v2: Probably some more patches could be squashed together. There might also
    be more places that should be addressed in these patches.

    - Whitespace fixes
    - Updated module-init-tools to 3.16. I'm not applying the ignore*.patch
    (it didn't apply).
    - Do not provide virtual/*/depmod-2.6; just provide virtual/*/depmod.
    - Do only install as depmod.
    - Rearrange the order of some patches.
    - Added patches to clean up (partly) task-base, distro_tracking_fields.

    A few of the patches might be ready to pull, but the majority will need
    to be revised.

===============
This work is unfinished and incomplete...
It is published in its current form both to get feedback, but also to aid
anyone else who is working on 3.0-support. If some of the patches are found to
be OK, it's fine to cherrypick them.

The kernel-related classes has been modified to build a 3.0 kernel. The
patches has been simplified by removing support for the 2.4-series. (The
latter was suggested in an older mail thread:
http://www.mail-archive.com/openembedded-core@lists.openembedded.org/msg02682.html
).

The patches has been tested on linux-yocto_2.6.37 and a hacked version using
the linux-yocto-dev repository (using a 3.0-rcX). The latest versions has only
been built for qemuarm, prior iterations has also been built for qemux86.

Finally, no work has been done on the libc-linux-headers classes and recipes.

This third version fixes a bug introduced in v2. (task-base-pcmcia26
weren't found). The fix is incorporated in patch 0008 (task-base).

Sofar, I've only got positive feedback on v2. (some feedback off-list
(including some that probably should have been on-list if it hadn't
been for some gmane problems).

Unless I find some more problems, or get such reports, I plan to send
a pull request towards the end of this week.

Regards,
Anders

It looks good to me apart from some ordering and PR bump type issues. 

Where you change the depmod dependency for example, we really need to
rebuild module-init-tools at the same time so the binary changes name at
the right point in the series. Patch 4 and patch 2 therefore probably
need to be together with a PR bump. I also wondered what the patch to
module-init-tools you're removing does (and why you just disabled rather
than deleted it).

Looks good though! I'm trying to resist merging some of the standalone
bits straight away :)

Cheers,

Richard

You're right, of course there should have been a PR bump there. I'll fix it and
squash patch 4 into patch 2 before I'll send a pull request.

I left it in there of laziness, in case someone had objected to the disabling
of the patch. As I'm not really sure of the purpose of that patch, I'll delete
the patch before I send the pull request. Then we'll probably find out
if someone
had any need for that patch...

Thanks!
If you get too eager to cherrypick a few bits, it's no problem.
Otherwise you can
count on getting a pull request tomorrow.

Cheers,
Anders
