Subject: [PATCH 36/38] unicore32: drop pte_file()-related helpers
Date: Wed, 24 Dec 2014 14:22:44 +0200 [thread overview]
Message-ID: <1419423766-114457-37-git-send-email-kirill.shutemov@linux.intel.com> (raw)
In-Reply-To: <1419423766-114457-1-git-send-email-kirill.shutemov@linux.intel.com>
We've replaced remap_file_pages(2) implementation with emulation.
Nobody creates non-linear mapping anymore.
