From 556269c138a8b2d3f5714b8105fa6119ecc505f2 Mon Sep 17 00:00:00 2001 From: Toshi Kani Date: Thu, 4 Jun 2015 18:55:16 +0200 Subject: arch/*/io.h: Add ioremap_wt() to all architectures Add ioremap_wt() to all arch-specific asm/io.h headers which define ioremap_wc() locally. These headers do not include . Some of them include , but ioremap_wt() is defined for consistency since they define all ioremap_xxx locally. In all architectures without Write-Through support, ioremap_wt() is defined indentical to ioremap_nocache(). frv and m68k already have ioremap_writethrough(). On those we add ioremap_wt() indetical to ioremap_writethrough() and defines ARCH_HAS_IOREMAP_WT in both architectures. The ioremap_wt() interface is exported to drivers.
