[PATCH 0/2] arm64/mm: Standardize printing for pgtable entries

From: Anshuman Khandual

Date: Tue Sep 01 2026 - 02:58:53 EST


Standardize printing for pgtable entries using recently introduced generic
helper ptval_bytes_to_hex_str() in core MM which automatically enables 128
bits entries when added later.

But first move __check_safe_pte_update() outside <asm/pgtable.h> to avoid
a cyclic dependency while accessing these afore mentioned core MM helpers
defined in <linux/pgtable.h>. This replaces the original page table entry
print standardisation proposal which was earlier part of the D128 series.

This series applies on v7.3-rc1 but after the following.
