Thanks for the reminder! I ended forgetting about it.
Last week was hard for me, as I had several things to solve
before taking some vacations, including preparing for a talk on
an user's group that happened last Saturday.

In any case, Linus already pulled from my tree:

	https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=fab0fca1da5cdc48be051715cd9787df04fdce3a

So, I guess the best would be to either let Linus know about that
when he would be pulling from arm-soc, or to solve such conflict 
between upstream and arm-soc.

As I'm in PTO those days, in order to avoid further conflicts with
linux-next, I'll pull from Linus tree today.

Thanks,
Mauro
