Subject: [PATCH v5 0/2] Tegra ADMA fixes

- Kernel test robot reported the build errors on 32-bit platforms due to
plain 64-by-32 division. Fix build error by using div_u64()

- Additional check for adma max page

Changelog
=========

v1 -> v2:
   * Used lower_32_bits() to truncate the 64-bit address space for
     division
   * Included additional patch to check for adma max page

v2 -> v3:
   * Removed unwanter file change

v3 -> v4:
   * Used div_u64() to perform the 64-bit division of adma address
     differences

v4 -> v5:
   * Updated commit message of the patchsets
