Hello,
This is merge of https://patchwork.ozlabs.org/cover/1162376/ (except two
last experimental patches) and
https://patchwork.ozlabs.org/patch/1162079/ rebased on top of master.
There was minor conflict in Makefile in the latter series.
Refreshed the patchset to fix build error on ppc32 and ppc64e.
Thanks
Michal
