We passed the address of swapper_pg_dir and this is what we got.

Nov  8 12:29:35 i2 kernel: The swapper_pg_dir address is
Nov  8 12:29:35 i2 kernel: The pgd offset is 280 address of pgd entry is
a0000001008d6000 value @ pgd entry is 2146033664
Nov  8 12:29:35 i2 kernel: The pmd offset is 201 pmd address is
value @ pmd is 0
