[PATCH] VM accounting fix
From: Hugh Dickins <hugh@veritas.com>

mprotect() fails to merge VMAs because one VMA can end up with
VM_ACCOUNT flag set, and another without that flag. That makes several
apps of mine to malfuncate.
Great find! Someone has got their test the wrong way round. Since that
VM_MAYACCT macro is being used in one place only, and just hiding what it's
actually about, fold it into its callsite.
