The goal was to eliminate dependencies on linux/mm.h from other popular headers such as highmem.h and dma-mapping.h, and I started by checking which symbols were really used and moved those declarations to separate slim headers. --- v1 -> v2: added more explanations to commit messages; renamed several new headers from page_*.h to folio_*.h as suggested by Matthew Wilcox; rebase on linux-next; fix build failures on architectures um,nios2,hexagon by adding more missing includes Max Kellermann (14): drivers: add missing includes on linux/mm.h (and others) include/drm/drm_gem.h: add poll_table_struct forward declaration linux/mm.h: move page_kasan_tag() to mm/page_kasan_tag.h linux/mm.h: move section functions to mm/page_section.h linux/mm.h: move page_address() and others to mm/page_address.h linux/mm.h: move folio_size(), ... to mm/folio_size.h linux/mm.h: move folio_next() to mm/folio_next.h linux/mm.h: move devmap-related declarations to mm/devmap_managed.h linux/mm.h: move usage count functions to mm/folio_usage.h linux/mm.h: move page_zone_id() and more to mm/folio_zone.h linux/mm.h: move pfmemalloc-related functions to pfmemalloc.h linux/mm.h: move is_vmalloc_addr() to mm/vmalloc_addr.h linux/mm.h: move high_memory to mm/high_memory.h include: reduce dependencies on linux/mm.h MAINTAINERS | 1 + arch/arm/include/asm/memory.h | 4 + arch/arm/include/asm/pgtable.h | 2 + arch/arm/mm/iomap.c | 3 + arch/csky/include/asm/page.h | 1 + arch/hexagon/include/asm/mem-layout.h | 4 + arch/m68k/include/asm/page_mm.h | 1 + arch/m68k/include/asm/pgtable_mm.h | 1 + arch/parisc/include/asm/floppy.h | 1 + arch/powerpc/include/asm/book3s/32/pgtable.h | 4 + arch/powerpc/include/asm/nohash/32/pgtable.h | 1 + arch/powerpc/include/asm/page.h | 1 + arch/x86/include/asm/floppy.h | 1 + arch/x86/include/asm/pgtable_32_areas.h | 4 + drivers/comedi/comedi_buf.c | 1 + .../qat/qat_common/adf_gen4_pm_debugfs.c | 1 + drivers/dma/dma-axi-dmac.c | 1 + drivers/dma/sh/rcar-dmac.c | 1 + drivers/firmware/qcom/qcom_scm-legacy.c | 1 + drivers/firmware/qcom/qcom_scm-smc.c | 1 + drivers/firmware/raspberrypi.c | 1 + drivers/iio/buffer/industrialio-buffer-dma.c | 1 + drivers/iommu/iommufd/ioas.c | 2 + drivers/iommu/iommufd/selftest.c | 1 + drivers/media/platform/mediatek/vpu/mtk_vpu.c | 1 + drivers/media/platform/ti/omap/omap_voutlib.c | 1 + drivers/misc/bcm-vk/bcm_vk_dev.c | 1 + drivers/misc/fastrpc.c | 1 + drivers/misc/genwqe/card_dev.c | 1 + drivers/misc/uacce/uacce.c | 1 + drivers/mtd/nand/onenand/onenand_samsung.c | 1 + drivers/mtd/spi-nor/core.h | 2 + drivers/pci/p2pdma.c | 1 + drivers/pci/pci.c | 1 + drivers/remoteproc/remoteproc_core.c | 1 + drivers/soc/qcom/rmtfs_mem.c | 1 + drivers/spi/spi-aspeed-smc.c | 1 + drivers/spi/spi-bcm2835.c | 2 + drivers/spi/spi-intel.c | 1 + drivers/virtio/virtio_ring.c | 1 + include/drm/drm_file.h | 1 + include/linux/bio.h | 2 + include/linux/dma-mapping.h | 1 + include/linux/highmem-internal.h | 2 + include/linux/highmem.h | 4 +- include/linux/huge_mm.h | 2 + include/linux/iommu.h | 1 + include/linux/mm.h | 582 +----------------- include/linux/mm/devmap_managed.h | 37 ++ include/linux/mm/folio_next.h | 27 + include/linux/mm/folio_size.h | 150 +++++ include/linux/mm/folio_usage.h | 177 ++++++ include/linux/mm/folio_zone.h | 38 ++ include/linux/mm/high_memory.h | 7 + include/linux/mm/page_address.h | 71 +++ include/linux/mm/page_kasan_tag.h | 66 ++ include/linux/mm/page_section.h | 23 + include/linux/mm/pfmemalloc.h | 52 ++ include/linux/mm/vmalloc_addr.h | 33 + include/linux/nvme-keyring.h | 2 + include/linux/scatterlist.h | 8 +- include/linux/skbuff.h | 4 + kernel/dma/ops_helpers.c | 1 + kernel/dma/remap.c | 1 + lib/scatterlist.c | 1 + mm/dmapool.c | 1 + 66 files changed, 777 insertions(+), 575 deletions(-) create mode 100644 include/linux/mm/devmap_managed.h create mode 100644 include/linux/mm/folio_next.h create mode 100644 include/linux/mm/folio_size.h create mode 100644 include/linux/mm/folio_usage.h create mode 100644 include/linux/mm/folio_zone.h create mode 100644 include/linux/mm/high_memory.h create mode 100644 include/linux/mm/page_address.h create mode 100644 include/linux/mm/page_kasan_tag.h create mode 100644 include/linux/mm/page_section.h create mode 100644 include/linux/mm/pfmemalloc.h create mode 100644 include/linux/mm/vmalloc_addr.h
