In any case, we'll continue to use the fact that mprotect is also
broken to get our WC mapping working (using mprotect PROT_NONE
followed by mprotect PROT_READ|PROT_WRITE causes the CD and WT bits
to get cleared). We're fortunate in this case that we've found a
bug to exploit that gives us the desired behaviour.

Nice-looking code - kgdb has improved rather a lot. I'm glad we
finally got it in. Maybe one day I'll get to use it again.

/me duly notes this request to break Andrew's systems even more frequently ;-)
