We are having build failure with linux-next for sparc allmodconfig with the error messages:
undefined reference to 'of_io_request_and_map'
CONFIG_OF is defined for sparc so it is expected that we have a definition of of_io_request_and_map() but of/address.c is only compiled if it is !SPARC. In other words, CONFIG_OF_ADDRESS is not defined for sparc so we get the build failure.
