Subject: [Qemu-devel] [PATCH v4 08/12] tcg: set up tb->page_addr before insertion
Date: Fri, 15 Jul 2016 20:58:48 +0300	[thread overview]
Message-ID: <20160715175852.30749-9-sergey.fedorov@linaro.org> (raw)
In-Reply-To: <20160715175852.30749-1-sergey.fedorov@linaro.org>

From: Alex Bennée <alex.bennee@linaro.org>

This ensures that if we find the TB on the slow path that tb->page_addr
is correctly set before being tested.
