Page mappings with full RWX permissions are a security risk. x86
has an option to walk the page tables and dump any bad pages.
(See e1a58320a38d ("x86/mm: Warn on W^X mappings")). Add a similar
implementation for arm64.

The page table dumping code always assumes it will be dumping to a
seq_file to userspace. The dumping code is useful in other situations.
Let the seq_file be optional.

Hi,
This is an implementation to check for writable and executable pages on arm64.
This is heavily based on the x86 version which uses the existing page table
dumping code to do the checking. Some notes:
- The W^X checking is important so this option should become defaut eventually.

Add two tips that describe --list option of config sub-command

Hi Johannes,
here's something quick to try or ponder about. However, untested since it's too

The previous patch has adjusted async compaction so that it helps against
longterm fragmentation when compacting for a non-MOVABLE high-order allocation.
The goal of this patch is to force such allocations go through compaction
once before being allowed to fallback to a pageblock of different migra
Preparation patch. We are going to need migratetype at lower layers than
compact_zone() and compact_finished().

The migrate scanner in async compaction is currently limited to MIGRATE_MOVABLE
pageblocks. This is a heuristic intended to reduce latency, based on the
assumption that non-MOVABLE pageblocks are unlikely to contain movable pages.
However, with the exception of THP's, most high-order allocations a
