If we do that now, will have merge conflicts. Thanks Yinghai Lu Yinghai Lu (7): 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, mm: setup page table from top-down x86, mm: Remove early_memremap workaround for page table accessing arch/x86/include/asm/page_types.h | 1 + arch/x86/include/asm/pgtable.h | 1 + arch/x86/kernel/setup.c | 3 + arch/x86/mm/init.c | 251 ++++++++++++------------------------ arch/x86/mm/init_32.c | 18 +++- arch/x86/mm/init_64.c | 100 ++++++--------- 6 files changed, 144 insertions(+), 230 deletions(-) -- 1.7.7
