------------------------------------------------------
From: Yunfeng Ye <yeyunfeng@xxxxxxxxxx>
Subject: mm/madvise.c: replace with page_size() in madvise_inject_error()
page_size() is supported after the commit a50b854e073c ("mm: introduce
page_size()").
Use page_size() in madvise_inject_error() for readability.
[akpm@xxxxxxxxxxxxxxxxxxxx: use ulong for `size', per David]
