From 97c9801a15e5b0c9a20e495b2ccabf010894e74b Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Sun, 11 Aug 2019 14:53:20 +0200 Subject: asm-generic: don't provide ioremap for CONFIG_MMU All MMU-enabled ports have a non-trivial ioremap and should thus provide the prototype for their implementation instead of providing a generic one unless a different symbol is not defined. Note that this only affects sparc32 nds32 as all others do provide their own version. Also update the kerneldoc comments in asm-generic/io.h to explain the situation around the default ioremap* implementations correctly.
