[PATCH] oskit-mach compiled without SMP

[Jeroen Dekkers]

Another fix for oskit without SMP support. It still doesn't work however, 
It displays while probing the IRQ of my ide drives and hangs. I'm making 
progress at least. :)

The patch is below, the gs register must be pushed because it's part of the
trap_state stuct passed to user_trap() and it is already popped when
returning to the interrupted thread. The syscall_trace things doesn't exist 
since debug_i386.c is removed from oskit-mach and should by removed.

If you're trying to compile oskit-mach, do "make kernel-ide" or something like
that, else it doesn't build. :)
