Subject: [PULL 01/15] memory: Log access direction for invalid accesses
Date: Wed, 13 Oct 2021 11:22:25 -0700	[thread overview]
Message-ID: <20211013182239.991127-2-richard.henderson@linaro.org> (raw)
In-Reply-To: <20211013182239.991127-1-richard.henderson@linaro.org>

From: BALATON Zoltan <balaton@eik.bme.hu>

In memory_region_access_valid() invalid accesses are logged to help
debugging but the log message does not say if it was a read or write.
Log that too to better identify the access causing the problem.
