At this point, I think reverting the changes would be an overreaction. 
Moreover, the change that I just made to vmparam.h on MIPS should
arguably have been made when 64-bit support was added to MIPS.  For
example, if someone had tried running ZFS on a 64-bit MIPS processor
just a few weeks or months ago, we would have discovered that the same
change was required.  In other words, the autoconfiguration changes are
bringing to light some problems that have been lurking within the
param.h and vmparam.h files on some of the non-x86/sparc64 platforms.

P.S. That said, I think we should exercise much caution in MFCing these
changes.
