Date: Fri, 30 Jan 2015 16:43:09 +0200 From: "Kirill A. Shutemov" <kirill.shutemov@...ux.intel.com> To: Andrew Morton <akpm@...ux-foundation.org> Cc: linux-mm@...ck.org, linux-kernel@...r.kernel.org, Guenter Roeck <linux@...ck-us.net>, "Kirill A. Shutemov" <kirill.shutemov@...ux.intel.com> Subject: [PATCH 00/19] expose page table levels on Kconfig leve I've failed my attempt on split up mm_struct into separate header file to be able to use defines from <asm/pgtable.h> to define mm_struct: it causes too much breakage and requires massive de-inlining of some architectures (notably ARM and S390 with PGSTE). This is other approach: expose number of page table levels on Kconfig level and use it to get rid of nr_pmds in mm_struct. Kirill A. Shutemov (19): alpha: expose number of page table levels on Kconfig level arm64: expose number of page table levels on Kconfig level arm: expose number of page table levels on Kconfig level frv: mark PUD and PMD folded ia64: expose number of page table levels on Kconfig level m32r: mark PMD folded m68k: mark PMD folded and expose number of page table levels mips: expose number of page table levels on Kconfig level mn10300: mark PUD and PMD folded parisc: expose number of page table levels on Kconfig level powerpc: expose number of page table levels on Kconfig level s390: expose number of page table levels sh: expose number of page table levels sparc: expose number of page table levels tile: expose number of page table levels um: expose number of page table levels x86: expose number of page table levels on Kconfig level mm: define default PGTABLE_LEVELS to two mm: do not add nr_pmds into mm_struct if PMD is folded arch/Kconfig | 4 ++++ arch/alpha/Kconfig | 4 ++++ arch/arm/Kconfig | 5 +++++ arch/arm64/Kconfig | 14 +++++++------- arch/arm64/include/asm/kvm_mmu.h | 4 ++-- arch/arm64/include/asm/page.h | 4 ++-- arch/arm64/include/asm/pgalloc.h | 8 ++++---- arch/arm64/include/asm/pgtable-hwdef.h | 6 +++--- arch/arm64/include/asm/pgtable-types.h | 12 ++++++------ arch/arm64/include/asm/pgtable.h | 8 ++++---- arch/arm64/include/asm/tlb.h | 4 ++-- arch/arm64/mm/mmu.c | 4 ++-- arch/frv/include/asm/pgtable.h | 2 ++ arch/ia64/Kconfig | 18 +++++------------- arch/ia64/include/asm/page.h | 4 ++-- arch/ia64/include/asm/pgalloc.h | 4 ++-- arch/ia64/include/asm/pgtable.h | 12 ++++++------ arch/ia64/kernel/ivt.S | 12 ++++++------ arch/ia64/kernel/machine_kexec.c | 4 ++-- arch/m32r/include/asm/pgtable-2level.h | 1 + arch/m68k/Kconfig | 4 ++++ arch/m68k/include/asm/pgtable_mm.h | 2 ++ arch/mips/Kconfig | 5 +++++ arch/mn10300/include/asm/pgtable.h | 2 ++ arch/parisc/Kconfig | 5 +++++ arch/parisc/include/asm/pgalloc.h | 2 +- arch/parisc/include/asm/pgtable.h | 17 ++++++++--------- arch/parisc/kernel/entry.S | 4 ++-- arch/parisc/kernel/head.S | 4 ++-- arch/parisc/mm/init.c | 2 +- arch/powerpc/Kconfig | 6 ++++++ arch/s390/Kconfig | 5 +++++ arch/s390/include/asm/pgtable.h | 2 ++ arch/sh/Kconfig | 4 ++++ arch/sparc/Kconfig | 4 ++++ arch/tile/Kconfig | 5 +++++ arch/um/Kconfig.um | 5 +++++ arch/x86/Kconfig | 6 ++++++ arch/x86/include/asm/paravirt.h | 8 ++++---- arch/x86/include/asm/paravirt_types.h | 8 ++++---- arch/x86/include/asm/pgalloc.h | 8 ++++---- arch/x86/include/asm/pgtable-2level_types.h | 1 - arch/x86/include/asm/pgtable-3level_types.h | 2 -- arch/x86/include/asm/pgtable.h | 8 ++++---- arch/x86/include/asm/pgtable_64_types.h | 1 - arch/x86/include/asm/pgtable_types.h | 4 ++-- arch/x86/kernel/paravirt.c | 6 +++--- arch/x86/mm/pgtable.c | 14 +++++++------- arch/x86/xen/mmu.c | 14 +++++++------- include/asm-generic/pgtable.h | 5 +++++ include/linux/mm_types.h | 2 ++ 51 files changed, 182 insertions(+), 117 deletions(-) -- 2.1.4 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
