-Subject: [PATCH] MIPS: kernel: fix sched_getaffinity with MT FPAFF enabled
-
-p->thread.user_cpus_allowed is zero-initialized and is only filled on
-the first sched_setaffinity call.
-
-To avoid adding overhead in the task initialization codepath, simply OR
-the returned mask in sched_getaffinity with p->cpus_allowed.
