[ Upstream commit 47cc75aa92837a9d3f15157d6272ff285585d75d ]
This ensures that no module record/or entry is added to the
unloaded_tainted_modules list if it does not carry a taint.

Currently, only the initial module that tainted the kernel is
recorded e.g. when an out-of-tree module is loaded.
The purpose of this patch is to allow the kernel to maintain a record of
each unloaded module that taints the kernel. So, in addition to
displaying a list of linked modules (see print_modules()) e.g. in the
event of a detected bad page, unloaded modules that carried a taint/or
taints are displayed too. A tainted module unload count is maintained.
The number of tracked modules is not fixed. This feature is disabled by
default.
