No. There is no way this topic can be "solved". The Adeos I-pipe patches
are meant to be applied to the mainline kernel. When you try to apply it
to some other tree, you get some issues.

The patch adeos-ipipe-2.6.31-arm-1.15-01-imx51.patch (which adds support
for IMX51) is meant to be applied to the rel_imx_2.6.31_10.02.00 relase.
It was not tested with any other release, so, yes, chances are that you
will get issues if you try and apply it to something else. If you want
to checkout the previous release, use git.

More information on this topic may be found in
ksrc/arch/arm/patches/README in Xenomai souces.
