Subject: [PATCH v2 5/7] powerpc/configs: Enable STRICT_MODULE_RWX in
 skiroot_defconfig

From: Russell Currey <ruscur@...sell.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.
