The patch titled
spufs: use find_first_bit() instead of sched_find_first_bit()
has been removed from the -mm tree. Its filename was
spufs-use-find_first_bit-instead-of-sched_find_first_bit.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: spufs: use find_first_bit() instead of sched_find_first_bit()
From: Masato Noguchi <Masato.Noguchi@xxxxxxxxxxx>
spu_sched->bitmap has MAX_PRIO(=140) width in bits.However, since
ff80a77f20f811c0cc5b251d0f657cbc6f788385, sched_find_first_bit() only supports
100-bit bitmaps.
Thus, spu_sched->bitmap should be treated by generic find_first_bit().
