  10 The kbuild test robot reported the following warning:
  11
  12   drivers/edac/altera_edac.c: In function 'ocram_free_mem':
  13   drivers/edac/altera_edac.c:1410:42: warning: cast from pointer to integer
  14         of different size [-Wpointer-to-int-cast]
  15     gen_pool_free((struct gen_pool *)other, (u32)p, size);
  16                                              ^
  17
  18 After adding support for ARM64 architectures, the unsigned long
  19 parameter is 64 bits and causes a build warning on 64-bit configs. Fix
  20 by casting to the correct size (unsigned long) instead of u32.
