[Intel-gfx] [PATCH 00/20] ILK+ interrupt improvements, v2

[Paulo Zanoni]

From: Paulo Zanoni <paulo.r.zanoni at intel.com>

Hi

This is basically a rebase of "[PATCH 00/19] ILK+ interrupt improvements", which
was sent to the mailing list on January 22. There are no real differences,
except for the last patch, which is new.

Original cover letter:
http://lists.freedesktop.org/archives/intel-gfx/2014-January/038679.html

The idea behind this series is that at some point our runtime PM code will just
call our irq_preinstall, irq_postinstall and irq_uninstall functions instead of
using dev_priv->pc8.regsave, so I decided to audit, cleanup and add a few WARNs
to our code before we do that change. We gotta be in shape if we want to be
exposed to runtime!

Thanks,
Paulo
