[PATCH] pid: export the symbols needed to use struct pid *
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.
