[SPARC64] mm: don't re-evaluate *ptep
sparc64 prom_callback and new_setup_frame32 each operates on a user page table without holding lock, and no doubt they've good reason. But I'd feel more confident if they were to do a "pte = *ptep" and then operate on pte, rather than re-evaluating *ptep. Signed-off-by: Hugh Dickins <hugh@veritas.com> Signed-off-by: David S.
