Subject: [PULL 5/5] exec: Fix overlap of PAGE_ANON and PAGE_TARGET_1
Date: Mon, 12 Apr 2021 11:31:52 +0100	[thread overview]
Message-ID: <20210412103152.28433-6-peter.maydell@linaro.org> (raw)
In-Reply-To: <20210412103152.28433-1-peter.maydell@linaro.org>

From: Richard Henderson <richard.henderson@linaro.org>

Unfortuately, the elements of PAGE_* were not in numerical
order and so PAGE_ANON was added to an "unused" bit.
As an arbitrary choice, move PAGE_TARGET_{1,2} together.

Cc: Laurent Vivier <laurent@vivier.eu>
Fixes: 26bab757d41b ("linux-user: Introduce PAGE_ANON")
