[PATCH 24/30] panic: Refactor the panic path

[Guilherme G. Piccoli]

Perfect Petr, thanks for your feedback!

I'll be out for some weeks, but after that what I'm doing is to split
the series in 2 parts:

(a) The general fixes, which should be reviewed by subsystem maintainers
and even merged individually by them.

(b) The proper panic refactor, which includes the notifiers list split,
etc. I'll think about what I consider the best solution for the
crash_dump required ones, and will try to split in very simple patches
to make it easier to review.

Cheers,


Guilherme
