I was going to implement the matching bits for i386, but never found
the time.  No point in my holding up your work any longer.  I am still
not clear on how this will handle threads but it sounds like CRIS
kernel bugs mean that that doesn't matter to you; it's irrelevant if
you've only got one copy of the debug registers.  I may come back to
revisit the names of the functions if anyone ever implements hardware
breakpoint support.

The patch is OK.  Please make sure to include a full changelog entry,
and update the copyright years in any files you touch.
