Subject: [PATCH 1/8] remap_range: make function 'remap_range' global
Date: Tue, 15 Jan 2013 14:48:43 +0100	[thread overview]
Message-ID: <1358257730-20579-2-git-send-email-alex.aring@gmail.com> (raw)
In-Reply-To: <1358257730-20579-1-git-send-email-alex.aring@gmail.com>

Change function remap_range in arm architecture to make it
global accessable. For example command 'memtest' can change
pte flags to enable or disable cache.

Add dummy function for others architectures that doesn't
have mmu or pte support.
