Thanks, Nick 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 *** BLURB HERE *** Nicholas Piggin (12): mm/vmalloc: fix vmalloc_to_page for huge vmap mappings 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: 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 | 10 + arch/arm64/include/asm/vmalloc.h | 25 + arch/arm64/mm/mmu.c | 26 - arch/powerpc/Kconfig | 1 + arch/powerpc/include/asm/vmalloc.h | 21 + arch/powerpc/kernel/module.c | 13 +- arch/powerpc/mm/book3s64/radix_pgtable.c | 21 - arch/x86/include/asm/vmalloc.h | 23 + arch/x86/mm/ioremap.c | 19 - arch/x86/mm/pgtable.c | 13 - include/linux/io.h | 9 - include/linux/vmalloc.h | 27 ++ init/main.c | 1 - mm/ioremap.c | 225 +-------- mm/memory.c | 66 ++- mm/page_alloc.c | 5 +- mm/vmalloc.c | 455 +++++++++++++++--- 18 files changed, 563 insertions(+), 399 deletions(-) -- 2.23.0
