Subject: [PATCH v2 2/2] lib: lz4: cleanup unaligned access efficiency detection
Date: Sat, 9 Apr 2016 22:05:35 +0100 [thread overview]
Message-ID: <1460235935-1003-3-git-send-email-rsalvaterra@gmail.com> (raw)
In-Reply-To: <1460235935-1003-1-git-send-email-rsalvaterra@gmail.com>
These identifiers are bogus. The interested architectures should define
HAVE_EFFICIENT_UNALIGNED_ACCESS whenever relevant to do so. If this
isn't true for some arch, it should be fixed in the arch definition.
