arm64/mm: move __check_safe_pte_update()

2026-10-05T06:37:07+00:00

Patch series "arm64/mm: Standardize printing for pgtable entries", v3. 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 to avoid a cyclic dependency while accessing these afore mentioned core MM helpers defined in . This replaces the original page table entry print standardisation proposal which was part of the D128 series [1]. This patch (of 2): The page table entry print helpers and related macros which are defined in will not be accessible in platform which is basically caused by cycling dependency. Move __check_safe_pte_update() inside arch/arm64/mm/mmu.c as a preparation for subsequent usage of the afore mentioned generic MM helpers. While here drop IS_ENABLED(CONFIG_DEBUG_VM), although wrap __check_safe_pte_update() inside #ifdef CONFIG_DEBUG_VM that preserves the current code optimization which is achieved via the static inline functions. This does not cause any functional change.

arm64: mte: make mte_save_tags() and mte_restore_tags() static

2026-10-05T06:35:33+00:00

mte_save_tags() and mte_restore_tags() are only used by arch_prepare_to_swap() and arch_swap_restore() in mteswap.c. Make them static and remove their declarations from mte.h. No functional change.

mm: drop pxd_ERROR()

2026-10-05T06:34:55+00:00

There are no more users left for any pxd_ERROR() either in generic MM or in the platform MM. Hence all these platform macros along with their generic fallback could be dropped across the tree.

Revert "arch: introduce set_direct_map_valid_noflush()"

2026-10-05T06:34:28+00:00

Commit 0c6378a71574 ("arch: introduce set_direct_map_valid_noflush()") added set_direct_map_valid_noflush() to allow updating the direct map for a physically contiguous range in execmem. As Brendan recently pointed out [1], this API is confusing because on arm64 it means that is sets VALID bit in ptes, while on other architectures it is an analog of set_direct_map_default_noflush(). The only user of set_direct_map_valid_noflush() was execmem's ROX cache freeing path and it was switched to utilize VM_FLUSH_RESET_PERMS for resetting permissions of the direct map alias. With the last user gone and with set_direct_map_{invalid,default}_noflush() accepting number of pages as a parameter, set_direct_map_valid_noflush() become a copy of set_memory_valid() on arm64 and a duplicate of set_direct_map_{invalid,default}_noflush() on other architecture, it is safe to remove set_direct_map_valid_noflush(). Also drop a stale comment in arm64::__kernel_map_pages() that Linus bothered to add when merging changes containing set_direct_map_valid_noflush() to his tree. This reverts commit 0c6378a71574daa6cd1534ad42a956e3262756c7.
