Subject: [PATCH v1 00/19] cleanup/refactor pgtable.h
Date: Mon, 11 Sep 2023 21:03:06 +0200 [thread overview]
Message-ID: <cover.1694443576.git.christophe.leroy@csgroup.eu> (raw)
This series is a cleanup of pgtable.h for nohash mainly
Main purpose is to refactor a lot of common code between
nohash/32 and nohash/64.
This series is a prerequisite for following series that will
rework PAGE flags and implement execute-only protection.
Christophe Leroy (19):
powerpc/8xx: Fix pte_access_permitted() for PAGE_NONE
powerpc/64e: Fix wrong test in __ptep_test_and_clear_young()
powerpc/40x: Remove stale PTE_ATOMIC_UPDATES macro
powerpc: Remove pte_ERROR()
powerpc: Deduplicate prototypes of ptep_set_access_flags() and
phys_mem_access_prot()
powerpc: Refactor update_mmu_cache_range()
powerpc: Untangle fixmap.h and pgtable.h and mmu.h
powerpc/nohash: Remove {pte/pmd}_protnone()
powerpc/nohash: Refactor declaration of {map/unmap}_kernel_page()
powerpc/nohash: Move 8xx version of pte_update() into pte-8xx.h
powerpc/nohash: Replace #ifdef CONFIG_44x by IS_ENABLED(CONFIG_44x) in
pgtable.h
powerpc/nohash: Refactor pte_update()
powerpc/nohash: Refactor checking of no-change in pte_update()
powerpc/nohash: Deduplicate _PAGE_CHG_MASK
powerpc/nohash: Deduplicate pte helpers
powerpc/nohash: Refactor ptep_test_and_clear_young()
powerpc/nohash: Deduplicate ptep_set_wrprotect() and
ptep_get_and_clear()
powerpc/nohash: Refactor pte_clear()
powerpc/nohash: Refactor __ptep_set_access_flags()
