Subject[PATCH v2 1/7] ARM: v7: allow setting different cache functions
Date
In preparation for adding support for the Broadcom Brahma-B15 read-ahead
cache which requires a different set of cache functions, allow the
__v7_proc macro to override the cache_fns settings, and default to
v7_cache_fns unless specified otherwise.
