Hey folks, this is an attempt to improve/refactor the dated panic notifiers
infrastructure. This is strongly based in a suggestion made by Pter Mladek [0]
some time ago, and it's finally ready. Below I'll detail the patch ordering,
testing made, etc.
First, a bit about the reason behind this.

The panic notifiers list is an infrastructure that allows callbacks to execute
during panic time. Happens that anybody can add functions there, no ordering
is enforced (by default) and the decision to execute or not such notifiers
before kdump may lead to high risk of failure in crash scenarios - default is
not to execute any of them. There is a parameter acting as a switch for that.
But some architectures require some notifiers, so..it's messy.

Patch 8 applied to powerpc/next.
