From: Rob Herring <redacted> With commit 75a675720d980d7 (ARM: 7838/1: Add check for Cortex-A15 errata 798181 ECO), !CONFIG_MMU builds fail to build: ../../arch/arm/kernel/setup.c:602:2: error: implicit declaration of function 'erratum_a15_798181_init' [-Werror=implicit-function-declaration] Fix this by moving the declarations for errata 798181 out of CONFIG_MMU ifdef. The errata work-around already depends on SMP, so other condition checks are not needed. Reported-by: Kevin Hilman <redacted> Signed-off-by: Rob Herring <redacted> --- Based on rmk's for-next branch.
