Subject: [PATCH 7/20] inflate: eliminate memzero usage
To: Andrew Morton <akpm@osdl.org>, linux-kernel@vger.kernel.org

inflate: replace call to memzero with simple loop

This is the only user of memzero in the inflate code and it's only for
16 bytes. Removing this lets us drop a copy of memzero from most
lib/inflate users.
