Thanks (it’s only temporary ;)).

Good question ;). In this particular case, there is an ongoing
discussion between Hanjun and Sudeep. While there isn’t anything
major, I would like to see some agreement and potentially an Ack from
the other party involved in the discussion (Sudeep).

There are other patches that are not specific to ARM, so it’s
really your decision. As for the general ARM(64) ACPI case, I don’t
think we have anyone in charge with deciding what’s correct or not
(BTW, who are the people active both in the _ARM_ Linux kernel community
and the ACPI standardisation forum?).

In the mean-time, I would like to see at least an ack from the arm-soc
team (Arnd and Olof) or them collecting those ARM-specific patches and
sending pull request to you. My biggest worry is how the ACPI standard
is interpreted by vendors and how (non-standard) features get into the 
Linux kernel.

Anyway, I’ll meet the Linaro guys in a week time and we’ll agree on
a way forward.

Thanks,

Catalin
