Subject: [PATCH] mm/debug:

When dumping struct page information, __dump_page() prints the page type
with a trailing blank followed by the page flags on a separate line:

anon
flags: 0x100000000090034(uptodate|lru|active|head|swapbacked)

Fix this by using pr_cont() instead of pr_warn() to get a single line:

anon flags: 0x100000000090034(uptodate|lru|active|head|swapbacked)
