    [MIPS] Fixe the definition of PTRS_PER_PGD · 5291925a
    Jack Tan 提交于
    When we use > 4KB's page size the original definition is not consistent
    with PGDIR_SIZE. For exeample, if we use 16KB page size the PGDIR_SHIFT is
    (14-2) + 14 = 26, PGDIR_SIZE is 2^26,so the PTRS_PER_PGD should be:
    
    	2^32/2^26 = 2^6
    
    but the original definition of PTRS_PER_PGD is 4096 (PGDIR_ORDER = 0).
    
    So, this definition needs to be consistent with the PGDIR_SIZE.
    
    And the new definition is consistent with the PGD init in pagetable_init().
