Subject: [PULL 01/24] target/arm: fix stage 2 page-walks in 32-bit emulation
Date: Mon, 23 Nov 2020 11:42:52 +0000	[thread overview]
Message-ID: <20201123114315.13372-2-peter.maydell@linaro.org> (raw)
In-Reply-To: <20201123114315.13372-1-peter.maydell@linaro.org>

From: Rémi Denis-Courmont <remi.denis.courmont@huawei.com>

Using a target unsigned long would limit the Input Address to a LPAE
page-walk to 32 bits on AArch32 and 64 bits on AArch64. This is okay
for stage 1 or on AArch64, but it is insufficient for stage 2 on
AArch32. In that later case, the Input Address can have up to 40 bits.
