From ff0c6eecef59d6f949bbc09d117f2527ae1d4e34 Mon Sep 17 00:00:00 2001 From: Luc Van Oostenryck Date: Tue, 31 Oct 2017 18:19:15 +0100 Subject: ARM: 8716/1: pass endianness info to sparse ARM depends on the macros '__ARMEL__' & '__ARMEB__' being defined or not to correctly select or define endian-specific macros, structures or pieces of code. These macros are predefined by the compiler but sparse knows nothing about them and thus may pre-process files differently from what gcc would. Fix this by passing '-D__ARMEL__' or '-D__ARMEB__' to sparse, depending on the endianness of the kernel, like defined by GCC. Note: In most case it won't change anything since most ARMs use little-endian (but an allyesconfig would use big-endian!).
