Hi,
The conversion to INITCALLS is ok (I have the same change here),
but I'm curious what problem you are solving with moving __init_begin and
__init_end to only include the .init.data.
If there is use of initcalls/data outside init then that is a bug and
should be fixed, not worked around.
There might however be another problem that Mikael Starvik told me about,
the padding between initdata and the next section had gone AWOL,
which made the free_initmem() destroy useful data.
With the attached patch (and a lot of other patches) I am successful in
booting an Axis Devboard82+.
Could you please try the included patch and see if that solves your problem?

I have a patch in the pipe that should fix this, will send it in just
a small while.

Thank you for your help!
