Subject[PATCH V2 0/2] mm/debug_vm_pgtable: Some minor updates
This series contains some cleanups and new test suggestions from Catalin
from an earlier discussion.

This series is based on v5.10-rc6 and has been tested on arm64 and x86 but
has only been build tested on riscv, s390, arc etc. It would be great if
folks could test this on these platforms as well. Thank you.

Changes in V2:

- Added some missing tests in pud_basic_tests()
- Added bidirectional dirty check after pxx_wrprotect() per Catalin
- Moved WARN_ON(pte_dirty(pte_wrprotect(pte))) just after page table entry creation

Changes in V1:

Anshuman Khandual (2):
mm/debug_vm_pgtable/basic: Add validation for dirtiness after write protect
mm/debug_vm_pgtable/basic: Iterate over entire protection_map[]
