5.0-stable review patch. If anyone has any objections, please let me know.
------------------ From: Qian Cai <c...@lca.pw> commit f5777bc2d9cf0712554228b1a7927b6f13f5c1f0 upstream. 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.
