[Xenomai-help] debian specific kernel patching/unpatching problems with 2.6.29

[Stefan Kisdaroczi]

Hi,

applying the xenomai kernelpatch created during debian package building
results to a corrupt init/Kconfig file and 'make menuconfig' fails. The 
problem
starts with linux-2.6.29.  reason: growing init/Kconfig file, see  [1].
This patch [2] fixed it (tested with 2.6.28 and 2.6.29).

The second problem is unpatching the kernel:
Starting with 2.6.29 the Adoes-IPipe patches have a second hunk for 
init/Kconfig
to remove the last line [3]. This hunk fails while reverse patching the 
kernel. Its
conflicting with the generated Kconfig.frag-patch (see [2] too).
Removing the second init/Kconfig-Hunk from the adeos-patch [3] fixed it.

tested with 2.5-rc2, but please merge to xenomai-2.4.x too. thank you.
kisda

Hi, why is this hunk needed ?

Thunderbird did massive whitespace damages to your patch it seems; could
you resend it attached? TIA,

No need to remove it, this hunk is ok, the second hunk was the problem,
