This series tries to access virtqueue metadata through kernel virtual
address instead of copy_user() friends since they had too much
overheads like checks, spec barriers or even hardware feature
toggling like SMAP. This is done through setup kernel address through
direct mapping and co-opreate VM management with MMU notifiers.

Test shows about 23% improvement on TX PPS. TCP_STREAM doesn't see
obvious improvement.

I'm still waiting for some review from mst.

If I don't see any review soon I will just wipe these changes from
patchwork as it serves no purpose to just let them rot there.

Thank you.

I thought we agreed I'm merging this through my tree, not net-next.
So you can safely wipe it.

Aha, I didn't catch that, thanks!
