From d025021e981fc2c06e95a3512f81f799f45d1f9c Mon Sep 17 00:00:00 2001 From: Clemens Gruber Date: Mon, 29 Aug 2016 17:10:36 +0200 Subject: [PATCH] gunzip: cache-align write buffer memory When using gzwrite to eMMC on an i.MX6Q board, the following warning occurs repeatedly: CACHE: Misaligned operation at range [4fd63318, 4fe63318] This patch cache-aligns the memory allocation for the gzwrite writebuf, therefore avoiding the misaligned dcache flush and the warning from check_cache_range.
