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.

v2 :
Fix a sender name of mail header, there was an mistake.
(from "jinb.park" to Jinbum Park)
Contents of patch-set are perfectly same.

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
