------------------------------------------------------
From: Hugh Dickins <hughd@xxxxxxxxxx>
Subject: mm: page_vma_mapped_walk(): use goto instead of while (1)
page_vma_mapped_walk() cleanup: add a label this_pte, matching next_pte,
and use "goto this_pte", in place of the "while (1)" loop at the end.
