955b12def4
The old mechanism to formatting proc files is extremely ugly. The seq_file API was designed specifically for cases like this and greatly simplifies the process. Also, most of the files in /proc really don't belong there. This patch introduces the infrastructure for putting these into debugfs and exposes all of the proc files in debugfs as well. This contains the i915 hooks rewrite as well, to make bisectability better.
