Subject: [PATCH 03/14] x86, ACPI: store override acpi tables phys addr
Date: Thu,  7 Mar 2013 20:58:29 -0800	[thread overview]
Message-ID: <1362718720-27048-4-git-send-email-yinghai@kernel.org> (raw)
In-Reply-To: <1362718720-27048-1-git-send-email-yinghai@kernel.org>

As later 32bit only find table with phys address during 32bit flat mode
in head_32.S.

To keep 32bit and 64 bit consistent, use phys_addr for all.

Use early_ioremap to access during copying.
