[PATCH 4/7] pid: Export the symbols needed to use struct pid *

["Eric W. Biederman" <ebiederm@xmission.com>]

pids aren't something that drivers should care about.
However there are a lot of helper layers in the kernel that do
care, and are built as modules.  Before I can convert them
to using struct pid instead of pid_t I need to export the
appropriate symbols so they can continue to be built.
