Hi Nhat,

As of today's mm-unstable (commit "c68cfbc5048e"), you can apply
patches in this order:

1) commit 64929fe8c0a4 ("crypto: acomp - Remove request chaining")
     from the cryptodev-2.6 tree. Or, Patch 0001 in this series that does
     the same.
2) Patch 0002 in this series.
3) Skip Patches 0003 and 0004 in this series, since they were not in
     mm-unstable when I created this patch series. They are now in
     mm-unstable.
4) Apply Patches 0005-0019 in this series.

Thanks,
Kanchana
