Subject: [RFC PATCH 0/2] ArmVirtQemu: unmap page #0 to catch NULL pointer dereferences
Date: Wed, 28 Nov 2018 20:16:44 +0100	[thread overview]
Message-ID: <20181128191646.31526-1-ard.biesheuvel@linaro.org> (raw)

Rationale in patch #2. Patch #1 is a prerequisite patch that ensures
that we no longer need page #0 to be mapped for the NOR flash driver
to be able to expose it as a read/write block device.
