[Intel-gfx] [PATCH] drm/i915/execlists: Pull the w/a LRI emission into a helper

[Joonas Lahtinen]

Quoting Chris Wilson (2018-06-18 12:41:50)
> Having the w/a registers as an open-coded table leaves a trap for the

> into a table, so that we only need add new registers to that table
> rather than try and remember important side-effects of earlier chunks of
> GPU instructions.

Not related to this patch, but the lack of OOB check for batch makes
one itch a little bit.
