[PATCH v4 01/40] ARM: mm: proc-macros: Add generic proc/cache/tlb struct definition macros

[Dave Martin]

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.

Currently, only a few things can be overriden when invoking the
macros, based on the overrides actually required by the existing
CPUs.  More overrides arguments can be added in the future, if
needed.
