Looks good. (I know found out what this is good for. Eventually, all booleans
in the source of DAC960 et al. should be changed to just 'bool' but that's
another patch's job.)

Looks good, except for the "all arches" thing. You only seem to add it
to i386:

Can someone please tell me what advantage 'define true true' is going to
bring, besides than being able to '#ifdef true'?
