From c9cf55285e87ac423c45d9efca750d3f50234d10 Mon Sep 17 00:00:00 2001

Subject: [PATCH] add poison.h and patch primary users

Localize poison values into one header file for better documentation and
easier/quicker debugging and so that the same values won't be used for
multiple purposes.

Use these constants in core arch., mm, driver, and fs code.
