Anybody with that old a CPU will have learnt to to say "no-hlt" or
whatever the kernel command line is, and we could probably retire the
silly old hlt check (which I'm not even sure really ever worked).
The one specific case I know precisely details of was the Cyrix 5510. A
hlt by the CPU on that chipset during an IDE DMA transfer hangs the
system forever.
Its some years since I've even seen a 5510 and that check could be
automated anyway
I think HLT for a die loop should be safe :)
