Subject: [PATCH 21/21] MAINTAINERS: Add Paul as context tracking maintainer

Since most of the bits have been imported from kernel/rcu/tree.c and
now that the context tracking code is tightly linked to RCU, add Paul
as a context tracking maintainer.

Also update the context tracking file header accordingly.
