commit: 60a1efc701a99db4ec497669986977d30eda503d [347/435] include/linux/generic-radix-tree.h: replace kernel.h with the necessary inclusions

compiler: gcc-9 (Debian 9.3.0-22) 9.3.0
reproduce (this is a W=1 build):
        # https://github.com/hnaz/linux-mm/commit/60a1efc701a99db4ec497669986977d30eda503d
        git remote add hnaz-mm https://github.com/hnaz/linux-mm

        git checkout 60a1efc701a99db4ec497669986977d30eda503d

Note: the hnaz-mm/master HEAD b8280145cf2a894c873fdf91fb2af474c52ac6cc builds fine.
      It only hurts bisectability.
