+Cc Ulf,

Javier,

First of all, thanks Javier for digging into the issue. Actually I have
Odroid U3 but because of user-space limitations (which I need for other
work) I cannot test all of mainline patches there.

Javier, Alim, Ulf,

I am not grabbing any more patches for v4.4 because I doubt that they
could be merged to arm-soc for this cycle. My last pull requests for
v4.4 is still pending...

This means that I plan to pick up these series for v4.5, after closing
v4.4 merge window (unless Kukjin picks it also). Because of that, we
have plenty of time, so my idea is:
1. Wait for some comments from Ulf on Javier's fix.
2. If the fix goes into v4.4, then problem solved.
3. If not and it get acked, then it can go with this set.
4. If not and it get applied by Ulf for v4.5, then a tag from him would
be a nice way to solve dependency.

Either way we don't have to hurry, I think.

Best regards,
Krzysztof
