[PATCH -V2 4/5] powerpc: mm: Only check for _PAGE_PRESENT in set_pte/pmd functions

2013-11-18 Thread Aneesh Kumar K.V
From: "Aneesh Kumar K.V" We want to make sure we don't use these function when updating a pte or pmd entry that have a valid hpte entry, because these functions don't invalidate them. So limit the check to _PAGE_PRESENT bit. Numafault core changes use these functions for updating _PAGE_NUMA bits.
