Subject: [PATCH] ACPI: Use early_memremap() instead of early_ioremap()
Date: Thu, 11 Jul 2013 02:29:15 +0800 [thread overview]
Message-ID: <51DDA7FB.1000801@gmail.com> (raw)
From: Zhang Yanfei <zhangyanfei@cn.fujitsu.com>
The mapping of acpi_tables_addr is obviously ordinary memory, so
use early_memremap() rather than early_iormeap().
