Looks good to me at a quick glance albeit Linus had second
thoughts about using fixmaps for this in the past. But with
delayed-flush for vmaps i think fixmaps are again the simpler
and more robust - albeit more limited - choice ...

In any case, the x86 tree already unified fixmap.h so could you
please resend the whole series as a 0/3, 1/3, 2/3, 3/3 thing
against tip:master, starting a new thread on lkml? (this thread
is already way too deep)
