Hi Luis,
This is based on the latest mcgrof/modules-next branch. I have decided
still to use RCU even though no entry is ever removed from the unloaded
tainted modules list. That being said, if I understand correctly, it is not
safe in some instances to use 'module_mutex' in print_modules(). So instead
we disable preemption to ensure list traversal with concurrent list
manipulation e.g. list_add_rcu(), is safe too.
Please let me know your thoughts.

module: Make module_flags_taint() accept a module's taints bitmap
directly
module: Introduce module unload taint tracking
