[PATCH] kernel/cpu: Distinct name for cpu_hotplug.dep_map

[Joonas Lahtinen <joonas.lahtinen@linux.intel.com>]

Hi Linus/Andrew,

This patch has been waiting for feedback or merging for ~8 months now.
It was posted to linux-kernel@vger.kernel.org initially and got an
immediate Acked-by. After no other feedback, I revised the assumed
maintainers and still no reactions. Next I changed over to
trivial@kernel.org and it was reviewed by Chris in the meanwhile,
but still no other feedback or merge (now 2 months).

I don't think sending the patch around endlessly is very productive,
or hammering same mailing lists/people repeatedly for that matter. So
I'd like to hear what's the correct channel for getting the patch in?

It has been dragged in a i915 testing branch to make CI lockdep splats
more readable.

Regards, Joonas

Use distinctive name for cpu_hotplug.dep_map to avoid the actual
cpu_hotplug.lock appearing as cpu_hotplug.lock#2 in lockdep splats.
