[PATCH v2 0/7] Various TLB and PTE improvements

[Nicholas Piggin]

I've posted most of these separately at one time or another but I
will send them as a series, there have been some bug fixes and
changelog and comment improvements, and got some more numbers.

Most of the patches are logically independent (except 2 and 3 AFAIKS).

Thanks,
Nick
