Subject: iommu/sva: include mmu_notifier.h header
Date: Mon, 5 Jan 2026 19:07:46 +0000

A call to mmu_notifier_arch_invalidate_secondary_tlbs() was introduced in commit e37d5a2d60a3 ("iommu/sva: invalidate stale IOTLB entries for kernel address space") but without explicitly adding its corresponding header file <linux/mmu_notifier.h>. This was evidenced while trying to enable compile testing support for IOMMU_SVA:

config IOMMU_SVA
select IOMMU_MM_DATA
- bool
+ bool "Shared Virtual Addressing" if COMPILE_TEST

The thing is for certain architectures this header file is indirectly included via <asm/tlbflush.h>. However, for others such as 32-bit arm the header is missing and it results in a build failure:

  $ make ARCH=arm allmodconfig
  [...]
  drivers/iommu/iommu-sva.c:340:3: error: call to undeclared function 'mmu_notifier_arch_invalidate_secondary_tlbs' [...]
    340 |  mmu_notifier_arch_invalidate_secondary_tlbs(iommu_mm->mm, start, end);
        |  ^

Fix this by including the appropriate header file.
