Turn the syscall interrupt into a trap (by switching the gate type.)
This leaves interrupts enabled while we're in the kernel, which is
precisely what we want.
This uncovered a horrendous problem with kernel tasks silently
overflowing their stacks. For now I've simply increased the stack size
but I need a more MMU-y solution for this eventually.
