Jacob Shin (4):
  x86/mm: find_early_table_space based on memory ranges that are being
    mapped
  x86: Only direct map addresses that are marked as E820_RAM
  x86: Fixup code testing if a pfn is direct mapped
  x86: if kernel .text .data .bss are not marked as E820_RAM, complain
    and fix

Yinghai Lu (2):
  x86, mm: Add page_size_mask()
  x86, mm: Split out split_mem_range
