From: Daniel Axtens Date: Wed, 18 May 2016 01:16:52 +0000 (+1000) Subject: powerpc/align: Use #ifdef __BIG_ENDIAN__ #else for REG_BYTE X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=a9650e9bc53239c30c39f77d9d8541e84641298a;p=linux-beck.git powerpc/align: Use #ifdef __BIG_ENDIAN__ #else for REG_BYTE Sparse complains that it doesn't know what REG_BYTE is: arch/powerpc/kernel/align.c:313:29: error: undefined identifier 'REG_BYTE' REG_BYTE is defined differently based on whether we're compiling for LE, BE32 or BE64. Sparse apparently doesn't provide __BIG_ENDIAN__ or __LITTLE_ENDIAN__, which means we get no definition. Rather than check for __BIG_ENDIAN__ and then separately for __LITTLE_ENDIAN__, just switch the #ifdef to check for __BIG_ENDIAN__ and then #else we define the little endian version. Technically that's dicey because PDP_ENDIAN is also a possibility, but we already do it in a lot of places so one more hardly matters.
