The task_struct->pid member is going to be deprecated, so start
using the helpers (task_pid_nr/task_pid_vnr/task_pid_nr_ns) in
the kernel.
The first thing to start with is the pid, printed to dmesg - in
this case we may safely use task_pid_nr(). Besides, printks produce
more (much more) than a half of all the explicit pid usage.

Andrew, this patch changes many code in drivers and file systems,
so it may cause many conflicts with other fixes in -mm tree. Is
there any way I can help with it, e.g. split it into pieces, wait
till another -mm tree or something else?
