In [1] Peter had a suggestion to broadly mute hotplug lockdep warnings during
init instead of going after every single warning and wrapping them with
cpus_read_{lock, unlock}(). This is implemented in [PATCH 1/2].

[PATCH 2/2] is a logical follow-up as [PATCH 1/2] is the generalized version
of the reverted patch.

Gentle ping - I suppose this flew under the holidays radar.
