commit f5777bc2
category: bugfix
bugzilla: 13472
CVE: NA

------------------------------------------------

Due to has_unmovable_pages() taking an incorrect irqsave flag instead of
the isolation flag in set_migratetype_isolate(), there are issues with
HWPOSION and error reporting where dump_page() is not called when there
is an unmovable page.
