There are more things to be added to TLB invalidation. Before doing that,
move the code to its own file, and add the relevant documentation.
Patch 1 fixes vma_invalidate_tlb() logic to make it update the right var;
Patch 2 only moves the code and do some function renames. No functional
change;
Patch 3 adds documentation for the TLB invalidation algorithm and functions.
---
v3:
- Added a fix for an issue from the last TLB patch series;
- included a better description about the changes on patch 2;
- did some minor fixes at kernel-doc markups;
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.
