Hi, Le 13/03/2024 à 05:21, Rohan McLure a écrit : > Replace occurrences of p{u,m,4}d_is_leaf with p{u,m,4}_leaf, as the > latter is the name given to checking that a higher-level entry in > multi-level paging contains a page translation entry (pte) throughout > all other archs. There's already an equivalent commit in mm-stable, that will likely go into v6.9: https://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm.git/commit/?h=mm-stable&id=bd18b688220c7225fb50498dabd9f9d0c9988e67 > > Reviewed-by: Christophe Leroy <christophe.leroy@csgroup.eu> > Signed-off-by: Rohan McLure <rmclure@linux.ibm.com> > --- > v9: No longer required in order to implement page table check, just a > refactor. > v10: Fix more occurances, and just delete p{u,m,4}_is_leaf() stubs as > equivalent p{u,m,4}_leaf() stubs already exist. > --- > arch/powerpc/include/asm/book3s/64/pgtable.h | 10 ++++---- > arch/powerpc/include/asm/pgtable.h | 24 -------------------- > arch/powerpc/kvm/book3s_64_mmu_radix.c | 12 +++++----- > arch/powerpc/mm/book3s64/radix_pgtable.c | 14 ++++++------ > arch/powerpc/mm/pgtable.c | 6 ++--- > arch/powerpc/mm/pgtable_64.c | 6 ++--- > arch/powerpc/xmon/xmon.c | 6 ++--- > 7 files changed, 26 insertions(+), 52 deletions(-) > > diff --git a/arch/powerpc/include/asm/book3s/64/pgtable.h b/arch/powerpc/include/asm/book3s/64/pgtable.h > index 62c43d3d80ec..382724c5e872 100644 > --- a/arch/powerpc/include/asm/book3s/64/pgtable.h > +++ b/arch/powerpc/include/asm/book3s/64/pgtable.h > @@ -1443,16 +1443,14 @@ static inline bool is_pte_rw_upgrade(unsigned long old_val, unsigned long new_va > /* > * Like pmd_huge() and pmd_large(), but works regardless of config options > */ > -#define pmd_is_leaf pmd_is_leaf > -#define pmd_leaf pmd_is_leaf > -static inline bool pmd_is_leaf(pmd_t pmd) > +#define pmd_leaf pmd_leaf > +static inline bool pmd_leaf(pmd_t pmd) > { > return !!(pmd_raw(pmd) & cpu_to_be64(_PAGE_PTE));
