From 4c73e8926623ca0f64c2c6111289ab8096fa647a Mon Sep 17 00:00:00 2001 From: "Luis R. Rodriguez" Date: Tue, 28 Jul 2015 20:17:13 +0200 Subject: [PATCH] arch/*/io.h: Add ioremap_uc() to all architectures This adds ioremap_uc() only for architectures that do not include asm-generic.h/io.h as that already provides a default definition for them for both cases where you have CONFIG_MMU and you do not, and because of this, the number of architectures this patch address is less than the architectures that the ioremap_wt() patch addressed, "arch/*/io.h: Add ioremap_wt() to all architectures"). In order to reduce the number of architectures we have to modify by adding new architecture IO APIs we'll have to review the architectures in this patch, see why they can't add asm-generic.h/io.h or issues that would be created by doing so and then spread a consistent inclusion of this header towards the end of their own header. For instance arch/metag includes the asm-generic/io.h *before* the ioremap*() definitions, this should be the other way around but only once we have guard wrappers for the non-MMU case also for asm-generic/io.h.
