-Subject: [PATCH] Revert "MIPS: BCM63xx: Provide a plat_post_dma_flush hook"
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8

-This reverts commit 3cf29543413207d3ab1c3f62a88c09bb46f2264e ("MIPS:
-BCM63xx: Provide a plat_post_dma_flush hook") since this commit was
-found to prevent BCM6358 (early BMIPS4350 cores) and some BCM6368
-(BMIPS4380 cores) from booting reliably.
-
-Alvaro was able to track this down to an issue specifically located to
-devices that use the second thread (TP1) when booting. Since BCM63xx did
-not have a need for plat_post_dma_flush() hook before, let's just keep
-things the way they were.

-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.
