Subject: [kernel-hardening][PATCH 0/3] arm: Makes ptdump resuable and add WX
 page checking

Hi,

Page table dumping code for arm64-x86 is reusable,
and they have function for WX page checking.
But arm doesn't have that.

This path series are to makes ptdump reusable,
and add WX page checking for arm.
This is heavily based on arm64 version.

Jinbum Park (3):
  arm: mm: dump: make page table dumping reusable
  arm: mm: dump: make the page table dumping seq_file optional
  arm: mm: dump: add checking for writable and executable pages
