Chaotian,

I have applied this except the ARM patches (patch7 and patch10) as I
think those should go via ARM SoC (unless I get acks for them).

Regarding patch8, it didn't apply since it needed a re-base. This time
it was trivial to fix, so I decided to pick it up anyway.

Future wise I also advise you to significantly trim the cc/to list
when posting patches. Likely what happens when that many people are
requested for input, is that *none* cares. :-)

Thanks and kind regards!
Uffe
