Its filename was iommu-sva-include-mmu_notifierh-header.patch This patch was dropped because it was merged into the mm-hotfixes-stable branch of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm ------------------------------------------------------ From: Carlos Llamas 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 . 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 . 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.
