Subject: [PATCH -v4 00/13] x86, mm: init_memory_mapping cleanup
Date: Sun, 30 Sep 2012 00:57:11 -0700	[thread overview]
Message-ID: <1348991844-12285-1-git-send-email-yinghai@kernel.org> (raw)

Current kernel init memory mapping between [0, TOML) and [4G, TOMH)
Some AMD systems have mem hole between 4G and TOMH, around 1T.

According to HPA, we should only mapping ram range.

This patcheset:
1. Seperate calculate_table_space_size and find_early_page_table out with
   init_memory_mapping.

2. For all ranges, will allocate page table one time

3. init mapping for ram range one by one.

Could be found at:
git://git.kernel.org/pub/scm/linux/kernel/git/yinghai/linux-yinghai.git for-x86-mm

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

Yinghai Lu (9):
  x86, mm: Add global page_size_mask and probe one time only
  x86, mm: Split out split_mem_range from init_memory_mapping
  x86, mm: Move init_memory_mapping calling out of setup.c
  x86, mm: Revert back good_end setting for 64bit
  x86, mm: Find early page table buffer altogether
  x86, mm: Separate out calculate_table_space_size()
  x86, mm: Move down two calculate_table_space_size down.
  x86, mm: Set memblock initial limit to 1M
  x86, mm: Use func pointer to table size calculation and mapping
