[PATCH v2 0/2] Move TLB invalidation code for its own file and document it

From: Mauro Carvalho Chehab
Date: Fri Jul 29 2022 - 03:04:06 EST


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 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.
