Thanks Stephen. Looks like a conflict with 9c47011d3302 ("arm64: support batched/deferred tlb shootdown during page reclamation/migration") which restructured that code slightly. I have to respin my series anyway so will rebase on mm-unstable rather than v6.5-rc2. - Alistair Stephen Rothwell <sfr@xxxxxxxxxxxxxxxx> writes: > [[PGP Signed Part:Undecided]] > Hi all, > > After merging the mm tree, today's linux-next build (arm64 defconfig) > failed like this: > > In file included from arch/arm64/include/asm/pgtable.h:15, > from include/linux/pgtable.h:6, > from arch/arm64/include/asm/io.h:12, > from include/linux/io.h:13, > from include/acpi/acpi_io.h:5, > from include/linux/acpi.h:37, > from include/acpi/apei.h:9, > from include/acpi/ghes.h:5, > from include/linux/arm_sdei.h:8, > from arch/arm64/kernel/asm-offsets.c:10: > arch/arm64/include/asm/tlbflush.h: In function '__flush_tlb_page_nosync': > arch/arm64/include/asm/tlbflush.h:268:53: error: 'vma' undeclared (first use in this function); did you mean 'cma'? > 268 | mmu_notifier_arch_invalidate_secondary_tlbs(vma->vm_mm, uaddr & PAGE_MASK, > | ^~~ > | cma > > Caused by commit > > 8c2be11e06f4 ("mmu_notifiers: call arch_invalidate_secondary_tlbs() when invalidating TLBs") > > I have reverted that commit (and the following clear > one and the two > earlier ones - otherwise it would not buildfrom) for today.
