Subject: [PATCH 0/5] notifiers: split notifier.h into subsystem headers

Now we define all kinds of notifiers in notifier.h, this is not
necessary at all, since different subsystems use different
notifiers, they are almost non-related with each other.

This can also save much build time. Suppose I add a new netdevice
event, really I don't have to recompile all the source, just network
related. Without this patch, all the source will be recompiled.

I move the notify events near to their subsystem notifier registers,
so that they can be found more easily.

In case of conflicts, I hope Andrew Morton would take the whole
patchset, rather than different subsystem maintainers take their own.
