ok. Like the patch below?
Don't need the cli; we're already running with interrupts disabled.
I'd do:
while (1)
asm volatile("hlt");
... mostly on general principles.
At least with current GCC the volatile isn't strictly needed as its implied

remember if that used to be different for previous GCC versions? I tend to
also stick volatiles on them still...
