From: Franck Bui-Huu Date: Thu, 15 Feb 2007 13:21:36 +0000 (+0100) Subject: [MIPS] Rename CONFIG_BUILD_ELF64 into KBUILD_64BIT_SYM32 X-Git-Tag: v2.6.24-rc1~1455^2~74 X-Git-Url: http://pilppa.com/gitweb/?a=commitdiff_plain;h=054c51b4368648406f487f54b7ed6ba75bbb3f8b;p=linux-2.6-omap-h63xx.git [MIPS] Rename CONFIG_BUILD_ELF64 into KBUILD_64BIT_SYM32 This patch renames it for 3 reasons: - "CONFIG" pattern is used by Kconfig. Now this macro is no more defined by Kconfig but by Kbuild itself make this clear by translating "CONFIG" into "KBUILD". - "ELF32" word is improper because it is irrelevant to ELF format and it makes confusion with CONFIG_BOOT_ELF32. So translate it with SYM32. - Add "64BIT" part to make clear that this macro implies a 64 bits kernel.
