Dave Hansen 46a6e0cf1c x86/mpx: Clean up the code by not passing a task pointer around when unnecessary ... The MPX code can only work on the current task. You can not, for instance, enable MPX management in another process or thread. You can also not handle a fault for another process or thread. Despite this, we pass a task_struct around prolifically. This patch removes all of the task struct passing for code paths where the code can not deal with another task (which turns out to be all of them). This has no functional changes. It's just a cleanup.
