Thanks, looks good. I'll take it however after merge window.
There are no dependencies between patches therefore you could limit
the amount of people you CC. You put specific "Cc" fields in patch but
you did not use them and sent it to 40 addresses. The CC in the patch
has exactly this purpose - do not send everything to everyone...
Best regards,
Krzysztof

We have a floating patch for this:

Andreas: Can you please take a second look at the patchset submitted by Linus
Walleij and Russel for simplifying the Actions startup code?

This looks fine, if you resubmit, can you add a missing space between
"adding" and "missing"? This applies to all of your patches, so I am
assuming you somehow scripted that, which should be easy to fix.
With that changed:

Andreas wrote a version of simplifying secondary startup in the
same spirit as Russell's patches, and it's merged and all
is fine I think.
If this patch applied on top of the current upstream code I'd say
just forget about my patch and merge Wen's patch instead.

"ARM: owl: smp: Drop bogus holding pen"
platsmp.c looks just fine these days. Except for what Wei's patch is fixing,
of_node_put().

No. My patches are in my tree queued for this merge window. They
are part of a series that can not be broken up and merged separately
because all the per-platform patches need to be merged before the final
patch "ARM: smp: remove arch-provided "pen_release"" otherwise the
platforms break. I thought that was already explained.
