Sorry for the nose please drop this patch, it causes build failure,

drivers/tty/sysrq.c:58:23: error: weak declaration of
âplatform_sysrq_reset_seqâ must be public
 static unsigned short platform_sysrq_reset_seq[] __weak = { KEY_RESERVED };
                       ^
drivers/tty/sysrq.c:59:12: error: weak declaration of
âsysrq_reset_downtime_msâ must be public
 static int sysrq_reset_downtime_ms __weak;
            ^
