Subject: [PATCH v5 07/38] ArmVirtPkg: Enable stack guard
Date: Mon, 13 Mar 2023 18:16:43 +0100
Message-Id: <20230313171714.3866151-8-ardb@kernel.org>
X-Mailer: git-send-email 2.39.2

Enable the stack guard in ArmVirtPkg builds, so that stack overflows are
caught as they occur, rather than when they happen to hit a read-only
memory region.
