The implementation # included calling arch_enter/leave_lazy_mmu() calls. # # The patch removes the usage of arch_enter/leave_lazy_mmu() because # set_pte is not supposed to be used when updating a pte entry. Powerpc # architecture uses this rule to skip the expensive tlb invalidate which # is not needed when you are setting up the pte for the first time. See # commit 56eecdb912b5 ("mm: Use ptep/pmdp_set_numa() for updating # _PAGE_NUMA bit") for more details # # The patch also makes sure we are not using the interface to update a # valid/present pte entry by adding VM_WARN_ON check all the ptes we # are setting up. Furthermore, we add a comment to set_pte_filter to # clarify it can only update folio-related flags and cannot filter # pfn specific details in pte filtering. # # Removal of arch_enter/leave_lazy_mmu() also will avoid nesting of # these functions that are not supported. For ex: # # remap_pte_range() # -> arch_enter_lazy_mmu() # -> set_ptes() # -> arch_enter_lazy_mmu() # -> arch_leave_lazy_mmu() # -> arch_leave_lazy_mmu() # # Fixes: 9fee28baa601 ("powerpc: implement the new page table range API") # Signed-off-by: "Aneesh Kumar K.V" <aneesh.kumar@linux.ibm.com> # Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> # Link: https://msgid.link/20231024143604.16749-1-aneesh.kumar@linux.ibm.com # < /opt/cross/kisskb/korg/gcc-13.1.0-nolibc/sparc64-linux/bin/sparc64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-13.1.0-nolibc/sparc64-linux/bin/sparc64-linux-ld --version # < git log --format=%s --max-count=1 47b8def9358c5eb888e78b24b7e5b7f2e2e97b8e # make -s -j 160 ARCH=sparc64 O=/kisskb/build/powerpc-fixes_defconfig_sparc64-gcc13 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-13.1.0-nolibc/sparc64-linux/bin/sparc64-linux- defconfig # < make -s -j 160 ARCH=sparc64 O=/kisskb/build/powerpc-fixes_defconfig_sparc64-gcc13 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-13.1.0-nolibc/sparc64-linux/bin/sparc64-linux- help # make -s -j 160 ARCH=sparc64 O=/kisskb/build/powerpc-fixes_defconfig_sparc64-gcc13 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-13.1.0-nolibc/sparc64-linux/bin/sparc64-linux- olddefconfig # make -s -j 160 ARCH=sparc64 O=/kisskb/build/powerpc-fixes_defconfig_sparc64-gcc13 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-13.1.0-nolibc/sparc64-linux/bin/sparc64-linux- <stdin>:1519:2: warning: #warning syscall clone3 not implemented [-Wcpp] /opt/cross/kisskb/korg/gcc-13.1.0-nolibc/sparc64-linux/bin/sparc64-linux-ld: warning: arch/sparc/vdso/vdso-note.o: missing .note.GNU-stack section implies executable stack /opt/cross/kisskb/korg/gcc-13.1.0-nolibc/sparc64-linux/bin/sparc64-linux-ld: NOTE: This behaviour is deprecated and will be removed in a future version of the linker /opt/cross/kisskb/korg/gcc-13.1.0-nolibc/sparc64-linux/bin/sparc64-linux-ld: warning: arch/sparc/vdso/vdso32/vdso-note.o: missing .note.GNU-stack section implies executable stack /opt/cross/kisskb/korg/gcc-13.1.0-nolibc/sparc64-linux/bin/sparc64-linux-ld: NOTE: This behaviour is deprecated and will be removed in a future version of the linker WARNING: modpost: EXPORT symbol "_mcount" [vmlinux] version generation failed, symbol will not be versioned.
