Re: [uml-devel] Re: [PATCH]Modules support in 2.6: reaching the complete fix

[BlaisorBlade <blaisorblade_spam@yahoo.it>]

First, I tried without CONFIG_MODVERSIONS, and the panic doesn't happen(which 
was obvious, since the offending code is compiled #ifdef MODVERSIONS) and no 
other one appears. And the module loading works.

Only thing which obviously can't work is the umlgdb script; I need 2.6 Uml 
modules because I need to test a change to the 2.6 loop device(i.e. the 
partition support).

Yes, I understand you've tried(though I don't know why user code can't include 
even some kernel headers, but that's my fault).

Yes, but the general rule does some post-processing which is needed for 
modules. See scripts/Makefile.build:134 and following ones(around the 
"cmd_modversions" definition).

I'm going to try!

I understand this well(I'm aware of how are they born), but check and see that 
the RODATA macro, know, already includes them... so it's useless(if not 
harmful, but it shouldn't) to list them twice.
