From 11e3e8d6d9274bf630859b4c47bc4e4d76f289db Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Thu, 12 Oct 2017 17:31:46 +0200 Subject: elf_fdpic: fix unused variable warning The elf_fdpic code shows a harmless warning when built with MMU disabled, I ran into this now that fdpic is available on ARM randconfig builds since commit 50b2b2e691cd ("ARM: add ELF_FDPIC support"). fs/binfmt_elf_fdpic.c: In function 'elf_fdpic_dump_segments': fs/binfmt_elf_fdpic.c:1501:17: error: unused variable 'addr' [-Werror=unused-variable] This adds another #ifdef around the variable declaration to shut up the warning.
