Subject: [04/26] sh: Fix cached/uncaced address calculation in 29bit mode
Date: Fri, 18 Nov 2011 15:58:17 -0800 [thread overview]
Message-ID: <20111119000004.314069503@clark.kroah.org> (raw)
In-Reply-To: <20111119000026.GA6679@kroah.com>
3.0-stable review patch. If anyone has any objections, please let me know.
------------------
From: Nobuhiro Iwamatsu <nobuhiro.iwamatsu.yj@renesas.com>
commit dfd3b596fbbfa48b8e7966ef996d587157554b69 upstream.
In the case of 29bit mode, CAC/UNCAC_ADDR does not return a right address.
This revises this problem by using P1SEGADDR and P2SEGADDR in 29bit mode.
