Subject: [PATCH v6 5/5] powerpc/configs: Enable STRICT_MODULE_RWX in skiroot_defconfig
Date: Tue, 24 Dec 2019 16:55:45 +1100	[thread overview]
Message-ID: <20191224055545.178462-6-ruscur@russell.cc> (raw)
In-Reply-To: <20191224055545.178462-1-ruscur@russell.cc>

skiroot_defconfig is the only powerpc defconfig with STRICT_KERNEL_RWX
enabled, and if you want memory protection for kernel text you'd want it
for modules too, so enable STRICT_MODULE_RWX there.
