So which branch should I try out? Do you have one with all of the required patches so I can just do a 3.7-rc3 'git pull' and try it out? > > 1. use brk to mapping first PMD_SIZE range. > 2. top down to initialize page table range by range. > 3. get rid of calculate page table, and find_early_page_table. > 4. remove early_ioremap in page table accessing. > > v2: changes, update xen interface about pagetable_reserve, so not > use pgt_buf_* in xen code directly. > v3: use range top-down to initialize page table, so will not use > calculating/find early table anymore. > also reorder the patches sequence. > v4: add mapping_mark_page_ro to fix xen, also move pgt_buf_* to init.c > and merge alloc_low_page() > > could be found at: > git://git.kernel.org/pub/scm/linux/kernel/git/yinghai/linux-yinghai.git > for-x86-mm > > Yinghai Lu (15): > x86, mm: Align start address to correct big page size > x86, mm: Use big page size for small memory range > x86, mm: Don't clear page table if next range is ram > x86, mm: only keep initial mapping for ram > x86, mm: Break down init_all_memory_mapping > x86, xen: Add xen_mapping_mark_page_ro > x86, mm: setup page table in top-down > x86, mm: Remove early_memremap workaround for page table accessing on 64bit > x86, mm: Remove parameter in alloc_low_page for 64bit > x86, mm: Merge alloc_low_page between 64bit and 32bit > x86, mm: Move min_pfn_mapped back to mm/init.c > x86, mm, xen: Remove mapping_pagatable_reserve > x86, mm: Add alloc_low_pages(num) > x86, mm: only call early_ioremap_page_range_init() one time on 32bit > x86, mm: Move back pgt_buf_* to mm/init.c > > arch/x86/include/asm/init.h | 4 - > arch/x86/include/asm/pgtable.h | 1 + > arch/x86/include/asm/pgtable_types.h | 1 - > arch/x86/include/asm/x86_init.h | 2 +- > arch/x86/kernel/setup.c | 2 + > arch/x86/kernel/x86_init.c | 3 +- > arch/x86/mm/init.c | 321 +++++++++++++++------------------- > arch/x86/mm/init_32.c | 76 ++++++-- > arch/x86/mm/init_64.c | 119 ++++--------- > arch/x86/mm/mm_internal.h | 11 ++ > arch/x86/xen/mmu.c | 29 +--- > 11 files changed, 249 insertions(+), 320 deletions(-) > create mode 100644 arch/x86/mm/mm_internal.h > -- > To unsubscribe from this list: send the line "unsubscribe linux-kernel" in > the body of a message to majordomo@vger.kernel.org > More majordomo info at http://vger.kernel.org/majordomo-info.html > Please read the FAQ at http://www.tux.org/lkml/ >
