Fixes the following compiler warnings:

  mm/page_pinner.c:240:28: error: comparison of distinct pointer types
      ('typeof ((ts_usec)) *' (aka 'long long *') and 'uint64_t *'
      (aka 'unsigned long long *')) [-Werror,-Wcompare-distinct-pointer-types]
                unsigned long rem_usec = do_div(ts_usec, 1000000);
                                         ^~~~~~~~~~~~~~~~~~~~~~~~
