Greetings, 0day kernel testing robot got the below dmesg and the first bad commit is https://git.kernel.org/pub/scm/linux/kernel/git/mel/linux.git mm-pagealloc-bulk-allocator-noirq-v1r2 commit d51e7da61ae978338fff5f2ba8813736ac1ed070 Author: Mel Gorman <mgorman(a)techsingularity.net&gt; AuthorDate: Thu Dec 1 10:39:07 2016 +0000 Commit: Mel Gorman <mgorman(a)techsingularity.net&gt; CommitDate: Thu Dec 15 12:55:44 2016 +0000 mm, page_alloc: Split buffered_rmqueue buffered_rmqueue removes a page from a given zone and uses the per-cpu list for order-0. This is fine but a hypothetical caller that wanted multiple order-0 pages has to disable/reenable interrupts multiple times. This patch structures buffere_rmqueue such that it's relatively easy to build a bulk order-0 page allocator. There is no functional change.
