ARM: mm: proc-macros: Add generic proc/cache/tlb struct definition macros
This patch adds some generic macros to reduce boilerplate when declaring certain common structures in arch/arm/mm/*.S Thanks to Russell King for outlining what the define_processor_functions macro could look like. Signed-off-by: Dave Martin <dave.martin@linaro.org> Acked-by: Nicolas Pitre <nicolas.pitre@linaro.org>
