drivers/clocksource/sh_cmt.c:920:2: error: implicit declaration of function ‘ioremap_nocache’ [-Werror=implicit-function-declaration]
  cmt->mapbase = ioremap_nocache(mem->start, resource_size(mem));
  ^
drivers/clocksource/sh_cmt.c:920:15: warning: assignment makes pointer from integer without a cast [enabled by default]
  cmt->mapbase = ioremap_nocache(mem->start, resource_size(mem));
