The patch titled
Subject: mm: hwpoison: dump page for unhandlable page
has been removed from the -mm tree. Its filename was
mm-hwpoison-dump-page-for-unhandlable-page.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
From: Yang Shi <shy828301@xxxxxxxxx>
Subject: mm: hwpoison: dump page for unhandlable page
Currently just very simple message is shown for unhandlable page, e.g.
non-LRU page, like: soft_offline: 0x1469f2: unknown non LRU page type
5ffff0000000000 ()
It is not very helpful for further debug, calling dump_page() could show
more useful information.
Calling dump_page() in get_any_page() in order to not duplicate the call
in a couple of different places. It may be called with pcp disabled and
holding memory hotplug lock, it should be not a big deal since hwpoison
handler is not called very often.
