Since the above revert got queued in -stable, I assume you don't need commit 73e2d827a501 ("arm64: Initialize jump labels before setup_machine_fdt()") in stable either. Do you plan to fix the crng_ready() static branch differently? If you do, I'd like to revert the corresponding arm64 commit as well. It seems to be harmless but I'd rather not keep it if no longer needed. So please keep me updated whatever you decide. Thanks. -- Catalin _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
