drivers/clocksource/sh_mtu2.c:391:2: error: implicit declaration of function âioremap_nocacheâ [-Werror=implicit-function-declaration]
  mtu->mapbase = ioremap_nocache(res->start, resource_size(res));
  ^
drivers/clocksource/sh_mtu2.c:391:15: warning: assignment makes pointer from integer without a cast [enabled by default]
  mtu->mapbase = ioremap_nocache(res->start, resource_size(res));
