Subject: [PATCH v2 04/27] ARM: move virt<->phys translation to io.h
Date: Thu,  5 Mar 2015 22:49:56 +0100	[thread overview]
Message-ID: <1425592221-23774-6-git-send-email-dev@lynxeye.de> (raw)
In-Reply-To: <1425592221-23774-1-git-send-email-dev@lynxeye.de>

That's the place where Linux has them and other architectures would
implement this.

This will help in phasing out the direct usage of the ARM asm/mmu.h
header.
