From 7e90b74967ea54dbd6eb539e1cb151ec37f63d7f Mon Sep 17 00:00:00 2001 From: Masato Noguchi Date: Fri, 20 Jul 2007 21:39:43 +0200 Subject: [PATCH] [CELL] spufs: use find_first_bit() instead of sched_find_first_bit() 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().
