[PATCH] uml: fork cleanup
Fix the do_fork calling convention: normal arch pass the regs and the new sp value to do_fork instead of NULL. Currently the arch-independent code ignores these values, while the UML code (actually it's copy_thread) gets the right values by itself. With this patch, things are fixed up.
