Oh yes, I've now noticed that. I got confused by the superfluous test in
asm-i386/bugs.h. Although not a problem at the moment, it is possible to
compile with CONFIG_X86_WP_WORKS_OK not set and e.g. CONFIG_M586 set. The
question is whether we want to catch that case.

I don't think this will work, as CONFIG_M486 implies CONFIG_X86_INVLPG
and CONFIG_X86_BSWAP which do not work for NexGens, AFAIK.
