Before doing that, move the code to its own file, and add the relevant documentation. Patch 1 only moves the code and do some function renames. No functional change. Patch 2 adds documentation for the TLB invalidation algorithm and functions. --- v2: only patch 2 (kernel-doc) was modified: - The kernel-doc markups for TLB were added to i915.rst doc; - Some minor fixes at the texts; - Use a table instead of a literal block while explaining how the algorithm works. That should make easier to understand the logic, both in text form and after its conversion to HTML/PDF; - Remove mention for GuC, as this depends on a series that will be sent later.
