I would ask why you didn't say so sooner?  I only started looking into this a 
couple of days back, if I'd known it was causing problems I'd have got on 
with it rather than tinkering with pmap.

I believe that the aim of all this is:
That any arm binary should run on any arm architecture, without caring what 
kernel it's on.  To achieve this the kernel exports a common set of arm 
headers for both arm26 and arm32.

I believe that these are arm32 specific so we can use arm/arm32/sysarch.h

status of which changes?  I've not committed any changes to userland yet to 
do with getting the builds going.

It can't be shared fully, eg bin/ps needs NBPG which is different on arm26 
and arm32, so this maybe a case of a sysctl to return it.  But there's a lot 
of commonality between
