From 4ea494b528ac1b9df9f0c77ba49e3e8ee108d9ec Mon Sep 17 00:00:00 2001 From: Geert Uytterhoeven Date: Thu, 6 Dec 2012 18:12:17 +0000 Subject: MIPS: delay.c: Check BITS_PER_LONG instead of __SIZEOF_LONG__ When building a 32-bit kernel for RBTX4927 with gcc version 4.1.2 20061115 (prerelease) (Ubuntu 4.1.1-21), I get: arch/mips/lib/delay.c:24:5: warning: "__SIZEOF_LONG__" is not defined As a consequence, __delay() always uses the 64-bit "dsubu" instruction. Replace the check for "__SIZEOF_LONG__ == 4" by "BITS_PER_LONG == 32" to fix this.
