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