These are the remaining 3 patches that came from the original ftrace/livepatch module notifier patchset found here: https://lkml.org/lkml/2016/2/8/1180 Basically, the patchset does a bit of module.c cleanup (patch 1 and 2) in preparation for the klp_module_{coming,going} calls (patch 3). We decided to stop relying on the module notifier callchain in favor of hard-coding the appropriate livepatch function calls that handle coming and going modules. Hard-coding these calls will guarantee that ftrace and livepatch exit/initialization routines are called in the correct order without relying on module notifiers. The patches should be nearly exactly the same as those from the previous discussion, except in patch 3 I've added back the #if IS_ENABLED(CONFIG_LIVEPATCH) guard in livepatch.h, and in patch 2 I decided that it might be safer to change mod->state with the module mutex held. Patches based on linux-next.
