87c4696d57 ("mm/debug: Add tests validating architecture page .."): [ 1.395296] kernel BUG at include/linux/mm.h:2007!

by kernel test robot

Greetings, 0day kernel testing robot got the below dmesg and the first bad commit is https://github.com/0day-ci/linux/commits/Anshuman-Khandual/mm-debug-Add-t... commit 87c4696d57b5e380bc2720fdff0772b042462b7d Author: Anshuman Khandual <anshuman.khandual(a)arm.com> AuthorDate: Tue Dec 24 10:08:42 2019 +0530 Commit: 0day robot <lkp(a)intel.com> CommitDate: Wed Dec 25 18:02:30 2019 +0800 mm/debug: Add tests validating architecture page table helpers This adds tests which will validate architecture page table helpers and other accessors in their compliance with expected generic MM semantics. This will help various architectures in validating changes to existing page table helpers or addition of new ones. This test covers basic page table entry transformations including but not limited to old, young, dirty, clean, write, write protect etc at various level along with populating intermediate entries with next page table page and validating them. Test page table pages are allocated from system memory with required size and alignments. The mapped pfns at page table levels are derived from a real pfn representing a valid kernel text symbol. This test gets called right after page_alloc_init_late(). This gets build and run when CONFIG_DEBUG_VM_PGTABLE is selected along with CONFIG_VM_DEBUG. Architectures willing to subscribe this test also need to select CONFIG_ARCH_HAS_DEBUG_VM_PGTABLE which for now is limited to x86 and arm64. Going forward, other architectures too can enable this after fixing build or runtime problems (if any) with their page table helpers. Folks interested in making sure that a given platform's page table helpers conform to expected generic MM semantics should enable the above config which will just trigger this test during boot. Any non conformity here will be reported as an warning which would need to be fixed. This test will help catch any changes to the agreed upon semantics expected from generic MM and enable platforms to accommodate it thereafter.
