Yeah, the statement this time should be why do you keep _single :)
It don't really mind which one we keep, but having both and both
optional seems rather odd.
It would be more logic to implement _single on top of _page.. as
long as
we can still do sub-page mappings (needed on ppc64) which I think
we can
using the offset / size args of _page...
But that means more work changing the existing ppc64 backends :-) So
probably a worthwhile long term goal but what Becky did is ok for the
transition. I can look at fixing up the ppc64 ones to implement page
(and see if that causes any problem) some time after Plumbers conf.
Ok. But it would be good if we could add comments in the code for the
to be done later issues we noted so it's harder to forget it.
Will do as I respin.
Thanks!
