Subject: linux-next: build failure after merge of the mm tree

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'?

      |                                                     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.
