Subject: Re: Bug#464962: immediate crash on boot on TM5800

Thought some more about this, and since this probably means gcc will 
generate this for userspace code as well nowadays, tm5800 should 
probably be downgraded to a 586-class machine.  Hence the Linux policy 
of promoting it to a 686-class machine for having CMOV is actually 
incorrect, it doesn't have all the userspace-visible features of a 
686-class machine, lacking long NOP.
