I need ACKs from the ARM64 maintainers on patches [6-7/13] and
[13-14/14].


There's also a dependency on the arm64 for-next/core branch, so I've
been
largely ignoring this as far as 4.6 is concerned and was planning to
take
a proper look for 4.7 once the upcoming merge window is out of the way.


That would be 4.7 and 4.8 respectively I suppose?

Anyway, Catalin has ACKed all of them except for the [13/14], so
technically I can apply [1-12/14] now and then [13-14/14] can be
applied when they are ready.

Do you think there will be any problems with merging [6-7/14] into 4.7
via the ACPI tree?
I would defer to the arm64 maintainers for decisions about the arm64
specific parts of the patch set.  That said, many of the arm64 specific
patches depend on the arm64 for-next/core branch, so you would have to be
careful about merge ordering if you pull these in before the
for-next/core
branch is merged.

Fair enough.  I will wait for an update then.

Also FWIW, I plan on addressing Catalin's comments about 13/14 and
posting a
new version of the patch set in the next day or two.

OK, but in that case it won't be considered for 4.7 (at least not by
me), so I'd suggest sending it in the second half of the 4.7 merge
window (or about that time).

To be candid, I would very much like for you to pull in as many of the
patches as you are comfortable with as soon as possible.

I don't know where Will and Catalin stand on this, and their opinion is
obviously important, but getting 1-12/14 merged to v4.7 and deferring the
last two for v4.8 would simplify the whole process for me.  The drawback is
carrying dead code around until the final parts are merged.
That is not unheard of, however.

OK, I'll try to put the [1-12/14] into my linux-next branch early next
week and we'll see if that triggers any conflicts.
