Hello all,

I have been trying to make libkvm compile to the same binary on all
m68k ports (partly so we can share /usr on all m68k ports) and I've
run into a snag: sizeof(struct vmspace) varies per machine.

The problem is that kvm_proc.c uses "struct kinfo_proc" which
contains a "struct vmspace" which contains a "struct pmap" and
that last structure varies in size across (m68k) machines.

So, I'm looking for guidance on how to deal with this.  Some
possibilities I've thought of are:  (in no particular order)

* Contrive to make "struct pmap" the same size on all m68k
* Change "struct vmspace" so vm_pmap is a zero-length array
  of "struct pmap" things, with the actual storage allocation
  done with MD information about the size...
* Change "struct vmspace" to remove vm_pmap entirely
  (Some XXX marks in the code appear to indicate this
   may have been desired, but the change would affect
   almost every port, i.e. in locore.s ...)

Any suggestions?

Thanks,
Gordon
