Subject: [PATCH v6, part3 00/16] accurately calculate memory statisitic information
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 have been merged into
the main stream kernel and could also 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
V5->V6:
1) Change signature of free_reserved_area() according to Russell King's
suggestion to fix following build warnings.
2) rebase to v3.9-mmotm-2013-05-09-15-57
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
Patch 16:
A minor fix for AVR32 related to HZ
Jiang Liu (16):
mm: change signature of free_reserved_area() to fix building warnings
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
AVR32: fix building warnings caused by redifinitions of HZ
