The patch titled
Subject: mm,hwpoison: drop unneeded pcplist draining
has been removed from the -mm tree. Its filename was
mmhwpoison-drop-unneeded-pcplist-draining.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
From: Oscar Salvador <osalvador@xxxxxxx>
Subject: mm,hwpoison: drop unneeded pcplist draining
memory_failure and soft_offline_path paths now drain pcplists by calling
get_hwpoison_page.
memory_failure flags the page as HWPoison before, so that page cannot
longer go into a pcplist, and soft_offline_page only flags a page as
HWPoison if 1) we took the page off a buddy freelist 2) the page was
in-use and we migrated it 3) was a clean pagecache.
Because of that, a page cannot longer be poisoned and be in a pcplist.
