Richard,
Consider these patches for merging. I've been building and working
with these for 2 weeks now, and while they aren't perfect, they
work and we need more eyes on 2.6.37.
Does anyone with the right admin privs have time to look
into this ?

In other words, the 2.6.37 repo is only reachable by a ssh
based clone :)
When I get that working, I can fixup the SRCREV issue and
resubmit this for merge.
Cheers,

What we get is the following:
- factoring of the code into some reusable routines in the form
of a linux-yocto bbclass. The -stable, -devel and libc headers
recipes are all using this common code
- A new branching scheme for the 2.6.37 kernel that generalizes
the branch names and shows their hierarchy. The tools that
process the kernel needed a lot of 'unlearning' about the
old structure (this took a lot of my time working on this).
If this needs to be tweaked more, we can do it later, since
the big changes are done and agreed on, and we can't delay
scaling this out to more boards much longer.
- A -stable recipe that continues to build the 2.6.34 kernel
and a move of the main recipe to track the development
2.6.37-rc5 tree. The qemu* targets have their defaults
changed to 2.6.37-rc, while the hardware targets remain
on 2.6.34 for a bit longer. To ease the switch over, I
put the SRCREVs for 2.6.37 into the recipe itself. We
can move these as .37 becomes the default.
- perf is moved into a linux-tools.inc, we can add more to
this and re-use it more easily from here
- BSP boostrapping is streamlined (docs to follow).
The temporary commenting of the preferred libc-headers provider
was intentional. There is something strange happening when
headers are generated for 2.6.34 that was breaking libc builds.
To avoid holding up this series, we'll go with the default
libc headers for a short while.
I've built and booted all the qemu* targets on 2.6.37
(minimal and sato), I've built most of the hardware
targets. I noticed some strangeness with the mouse on
ARM, and that will need to be looked at further. I've done
some audits on the kernel configuration in 2.6.37, and
while it looks sane, full BSP testing will tell us if
anything major changed (that I missed).
If there are better suggestions on how we can stage and
get mileage on this code, I'm all ears, but this is a kernel
uprev, so I expect some issues (there always is even though
I've done plenty of these). If we don't want anything
destabilizing in the tree, I'm fine with this and we just
need to come up with a plan.
What remains (I'm only one person!):
- BSP porting and full BSP testing
- Investigation into the libc-headers issue
- Continued cleanup
- Feature merging into 2.6.37 (lttng, yaffs, etc)
