[PATCH v5, part3 00/15] accurately calculate memory statisitic information

[Jiang Liu]

The original goal of this patchset is to fix the bug reported by
https://bugzilla.kernel.org/show_bug.cgi?id=53501
Now it has also been expanded to reduce common code used by memory
initializion.

This is the third part, previous two patch sets could be accessed at:
http://marc.info/?l=linux-mm&m=136289696323825&w=2
http://marc.info/?l=linux-mm&m=136290291524901&w=2

This patchset applies to
git://git.cmpxchg.org/linux-mmotm.git v3.9-rc8-mmotm-2013-04-25-16-24

V2->V4:
1) rebase to git://git.cmpxchg.org/linux-mmotm.git
2) fix some build warnings and other minor bugs of previous patches

V4->V5:
1) rebase to v3.9-rc8-mmotm-2013-04-25-16-24
2) address comments from last round of review

We have only tested these patchset on x86 platforms, and have done basic
compliation tests using cross-compilers from ftp.kernel.org. That means
some code may not pass compilation on some architectures. So any help
to test this patchset are welcomed!

Patch 1-7:
	Bugfixes and more work for part1 and part2
Patch 8-9:
	Fix typo and minor bugs in mm core
Patch 10-14:
	Enhance the way to manage totalram_pages, totalhigh_pages and
	zone->managed_pages.
Patch 15:
	Report available pages within the node as "MemTotal" for sysfs
	interface /sys/.../node/nodex/meminfo

Jiang Liu (15):
  mm: fix build warnings caused by free_reserved_area()
  mm: enhance free_reserved_area() to support poisoning memory with
    zero
  mm/ARM64: kill poison_init_mem()
  mm/x86: use free_reserved_area() to simplify code
  mm/tile: use common help functions to free reserved pages
  mm, powertv: use free_reserved_area() to simplify code
  mm, acornfb: use free_reserved_area() to simplify code
  mm: fix some trivial typos in comments
  mm: use managed_pages to calculate default zonelist order
  mm: accurately calculate zone->managed_pages for highmem zones
  mm: use a dedicated lock to protect totalram_pages and
    zone->managed_pages
  mm: make __free_pages_bootmem() only available at boot time
  mm: correctly update zone->mamaged_pages
  mm: concentrate modification of totalram_pages into the mm core
  mm: report available pages as "MemTotal" for each NUMA node
