I have a question regarding the ipipe patches.  There appear to be three places to get them:

1) Contained within the Xenomai tar
2) From the gna adeos downloads page
3) From the DENX ipipe git

I have been getting the patches from the Xenomai tar, but I ran into a problem, because I needed to use a newer version of the kernel, to get some other powerpc features.  The patch from the Xenomai tar was not new enough to apply cleanly.

So, can I use the gna-ipipe patches with the Xenomai tar, or am I better off extracting a patch from the DENX ipipe git?

Even if you recommend the gna-ipipe patches, I'd like to know what git commands one would use to extract a patch file from the DENX ipipe git.  I assume it is some variant of git-diff, but I am still learning git, so a hint would be appreciated.

Also, I'm not clear on the best way to set up my local git tree.  Do I clone from linux-2.6-denx.git or ipipe-2.6.git?  Whichever I clone from, do I create branches to track both of those remote git repositories?  Once I apply the ipipe patch to my local git tree, do you recommend committing that, perhaps on some other branch?

I guess this boils down to: what is the "best practice" for setting up a local git given that I want Xenomai plus a very recent kernel.  I also want to be able to apply updates for ipipe, Xenomai, and the kernel, and I'm not clear on how that interacts with the ipipe patch model.  Do I back out one ipipe patch to apply a newer one, or somehow create a diff between two patches?  I'm so confused... :-)

    TIA for any guidance you can offer,
