[PATCH] uml: kludgy compilation fixes for x86-64 subarch modules support

These are some trivial fixes for the x86-64 subarch module support.  The only
potential problem is that I have to modify arch/x86_64/kernel/module.c, to
avoid copying the whole of it.

I can't use it verbatim because it depends on a special vmalloc-like area for
modules, which for now (maybe that's to fix, I guess not) UML/x86-64 has not.
I went the easy way and reused the i386 vmalloc()-based allocator.
