Hi Vinay (& list),

I had the same problem compiling a uml kernel 2.6.7 and 2.6.8.1. I took a 
debian kernel-source package and applied the uml-patch for it.

It seems that in ksyms.c "os_ioctl_generic" is declared twice. So I made a 
small patch for this problem.

I attached it as file to my mail, but because it's so short, I copy&paste it 
quite under my post.

It would be nice if a good kernel hacker would take a look at it. The UML 
works for me, but I'm not sure if I solved the problem correctly.

Patch (works for 2.6.7 and 2.6.8 with the uml patch applied):
