This somewhat controversial patchset converts internal arithmetic in the
memory API to 128 bits.

Given the level of controversy, what do you think about deferring
this to 1.1?

If it's deferred then one of my rearrangements for the arithmetic must
go in instead.  These patches fix real bugs, that bite us on pseries.
It's not the only way to fix those bugs, and probably not even my
personally preferred way to fix them, but they need to be fixed
_somehow_ for 1.0.

Yes, plus if one of them is exploitable, then it's certainly a must for 1.0.

Since it's just internal, I'll just pull this series and if we want to change it post 1.0, we can.
