The code in pgtable-64.h assumes TASK_SIZE is always bigger than a first level PGDIR_SIZE. This is not the case for 64K pages, where task size is 40 bits (1TB) and a pgd entry can map 42 bits. This leads to USER_PTRS_PER_PGD being zero for 64K pages. Signed-off-by: NPeter Watkins <treestem@gmail.com> Signed-off-by: NRalf Baechle <ralf@linux-mips.org>
