>Description:
The xen MD kernel has substantial chunks of code copied from
NetBSD/i386. In some of the modules that I have looked at, the
differences between the xen and i386 versions are trivial.

>How-To-Repeat:
Edit files under arch/i386, break xen, and notice that xen lags
behind i386.

>Fix:
Where the differences are trivial, they should be should be handled
with #ifdef blocks or architecture dependent functions.
