No doubt there will be a few more things but I can do incremental fixes for small things if this gets into -mm. Thanks, Nick Since v11: - ARM compile fix (patch 1) - debug_vm_pgtable compile fix Since v10: - Fixed code style, most > 80 colums, tweak patch titles, etc [thanks Christoph] - Made huge vmalloc code and data structure compile away if unselected [Christoph] - Archs only have to provide arch_vmap_p?d_supported for levels they implement [Christoph] Since v9: - Fixed intermediate build breakage on x86-32 !PAE [thanks Ding] - Fixed small page fallback case vm_struct double-free [thanks Ding] Since v8: - Fixed nommu compile. - Added Kconfig option help text - Added VM_NOHUGE which should help archs implement it [suggested by Rick] Since v7: - Rebase, added some acks, compile fix - Removed "order=" from vmallocinfo, it's a bit confusing (nr_pages is in small page size for compatibility). - Added arch_vmap_pmd_supported() test before starting to allocate the large page, rather than only testing it when doing the map, to avoid unsupported configs trying to allocate huge pages for no reason. Since v6: - Fixed a false positive warning introduced in patch 2, found by kbuild test robot. Since v5: - Split arch changes out better and make the constant folding work - Avoid most of the 80 column wrap, fix a reference to lib/ioremap.c - Fix compile error on some archs Since v4: - Fixed an off-by-page-order bug in v4 - Several minor cleanups. - Added page order to /proc/vmallocinfo - Added hugepage to alloc_large_system_hage output. - Made an architecture config option, powerpc only for now. Since v3: - Fixed an off-by-one bug in a loop - Fix !CONFIG_HAVE_ARCH_HUGE_VMAP build fail Nicholas Piggin (14): ARM: mm: add missing pud_page define to 2-level page tables mm/vmalloc: fix HUGE_VMAP regression by enabling huge pages in vmalloc_to_page mm: apply_to_pte_range warn and fail if a large pte is encountered mm/vmalloc: rename vmap_*_range vmap_pages_*_range mm/ioremap: rename ioremap_*_range to vmap_*_range mm: HUGE_VMAP arch support cleanup powerpc: inline huge vmap supported functions arm64: inline huge vmap supported functions x86: inline huge vmap supported functions mm/vmalloc: provide fallback arch huge vmap support functions mm: Move vmap_range from mm/ioremap.c to mm/vmalloc.c mm/vmalloc: add vmap_range_noflush variant mm/vmalloc: Hugepage vmalloc mappings powerpc/64s/radix: Enable huge vmalloc mappings .../admin-guide/kernel-parameters.txt | 2 + arch/Kconfig | 11 + arch/arm/include/asm/pgtable-3level.h | 2 - arch/arm/include/asm/pgtable.h | 3 + arch/arm64/include/asm/vmalloc.h | 24 + arch/arm64/mm/mmu.c | 26 - arch/powerpc/Kconfig | 1 + arch/powerpc/include/asm/vmalloc.h | 20 + arch/powerpc/kernel/module.c | 21 +- arch/powerpc/mm/book3s64/radix_pgtable.c | 21 - arch/x86/include/asm/vmalloc.h | 20 + arch/x86/mm/ioremap.c | 19 - arch/x86/mm/pgtable.c | 13 - include/linux/io.h | 9 - include/linux/vmalloc.h | 46 ++ init/main.c | 1 - mm/debug_vm_pgtable.c | 4 +- mm/ioremap.c | 225 +------- mm/memory.c | 66 ++- mm/page_alloc.c | 5 +- mm/vmalloc.c | 484 +++++++++++++++--- 21 files changed, 619 insertions(+), 404 deletions(-) -- 2.23.0
