Thanks!

Yes, it's about time.

OK, that's unfamiliar to me, but I'll try that out.

That brings up a question related to PATCH 11 in the series (MAINTAINERS
update); who will be maintaining arch/arm/mach-bcm/*brcmstb*, and how
will code go upstream? It seems like Matt and Christian are officially
mach-bcm maintainers, although I don't know if Christian is still
involved.

Also, BCM7xxx shares little in common with the rest of mach-bcm, except
a company name, so we'd really like at least the 'Maintainer' entries
for the CC. I was planning on a separate git tree too, although it could
have conflicts if we touch arch/arm/mach-bcm/{Makefile,Kconfig}.

So would we send a separate arm-soc pull request for the arm-soc
targeted changes (and all future development)?

I don't see much activity from the drivers/power/ maintainers on the
mailing lists, and I know David Woodhouse at least has been severely
distracted (I took over for him on driver/mtd/ recently), so I don't
expect much. (EDIT: I see [1]. Nice!)

I proposed an additional diff on that patch in response.

I can strip the drivers/power/reboot/ driver out and send it separately
to our new drivers/power/ maintainer (thanks Sebastian!), and hope that
it gets through for 3.17.

For the reset of mach-bcm stuff, I'll just send an arm-soc pull request
soon enough, unless Matt/Arnd/Olof object.

Thanks,
Brian
