The most complicated and invasive to me looks r321610 "8021 ARC buf data
scatter-ization".  It took 5 fix commits to make it behave in head, but
Andriy told me it should be good now, and I run it on my systems too.

I've merged all we had in head (except couple gptzfsboot commits
significantly increasing its size, that could break POLA).  Next round
will any way go to head first, so stable/11 should probably be idle for
a month at least and should be good for testing now.
