[Xenomai-help] How do you recommend installing ipipe patches?

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problem, because I needed to use a newer version of the kernel, to get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
<http://git.denx.de/?p=linux-2.6-denx.git;a=summary> or ipipe-2.6.git
<http://git.denx.de/?p=ipipe-2.6.git;a=summary>?  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,
    Steve
