Kees Cook	fff00db852	ARM: 8014/1: mm: fix reporting of read-only PMD bits ... On non-LPAE ARMv6+, read-only PMD bits are defined with the combination "PMD_SECT_APX | PMD_SECT_AP_WRITE". Adjusted the bit masks to correctly report this.

Kees Cook	cd91b2fecf	ARM: 7963/1: mm: report both sections from PMD ... On 2-level page table systems, the PMD has 2 section entries. Report these, otherwise ARM_PTDUMP will miss reporting permission changes on odd section boundaries.
