Peter Anvin" Cc: Andi Kleen , Dave Hansen , Andy Lutomirski , Dan Williams , linux-mm@kvack.org, linux-kernel@vger.kernel.org, "Kirill A. Shutemov" Here's silghtly revised version of the last bunch of of patches that brings initial 5-level paging enabling. Please review and consider applying. Changes since v5: - Added patch to re-apply switching x86 to generic GUP_fast(). It was reverted earlier from tip/mm due to regression. - X86_5LEVEL now conflicts with XEN_PV, not whole XEN. - Ack from Michal for the last patch. - Remove unused L4_START_KERNEL from head_64.S.

Shutemov (10): x86/mm/gup: Switch GUP to the generic get_user_page_fast() implementation x86/asm: Fix comment in return_from_SYSCALL_64 x86/boot/64: Rewrite startup_64 in C x86/boot/64: Rename init_level4_pgt and early_level4_pgt x86/boot/64: Add support of additional page table level during early boot x86/mm: Add sync_global_pgds() for configuration with 5-level paging x86/mm: Make kernel_physical_mapping_init() support 5-level paging x86/mm: Add support for 5-level paging for KASLR x86: Enable 5-level paging support x86/mm: Allow to have userspace mappings above 47-bits arch/arm/Kconfig | 2 +- arch/arm64/Kconfig | 2 +- arch/powerpc/Kconfig | 2 +- arch/x86/Kconfig | 8 + arch/x86/boot/compressed/head_64.S | 23 +- arch/x86/entry/entry_64.S | 3 +- arch/x86/include/asm/elf.h | 4 +- arch/x86/include/asm/mmu_context.h | 12 - arch/x86/include/asm/mpx.h | 9 + arch/x86/include/asm/pgtable-3level.h | 47 +++ arch/x86/include/asm/pgtable.h | 55 ++- arch/x86/include/asm/pgtable_64.h | 22 +- arch/x86/include/asm/processor.h | 12 +- arch/x86/include/uapi/asm/processor-flags.h | 2 + arch/x86/kernel/espfix_64.c | 2 +- arch/x86/kernel/head64.c | 143 +++++++- arch/x86/kernel/head_64.S | 131 ++------ arch/x86/kernel/machine_kexec_64.c | 2 +- arch/x86/kernel/sys_x86_64.c | 30 +- arch/x86/mm/Makefile | 2 +- arch/x86/mm/dump_pagetables.c | 2 +- arch/x86/mm/gup.c | 496 ---------------------------- arch/x86/mm/hugetlbpage.c | 27 +- arch/x86/mm/init_64.c | 108 +++++- arch/x86/mm/kasan_init_64.c | 12 +- arch/x86/mm/kaslr.c | 81 +++-- arch/x86/mm/mmap.c | 6 +- arch/x86/mm/mpx.c | 33 +- arch/x86/realmode/init.c | 2 +- arch/x86/xen/Kconfig | 1 + arch/x86/xen/mmu_pv.c | 16 +- arch/x86/xen/xen-pvh.S | 2 +- mm/Kconfig | 2 +- mm/gup.c | 10 +- 34 files changed, 605 insertions(+), 706 deletions(-) delete mode 100644 arch/x86/mm/gup.c -- 2.11.0 -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
