Subject: [PATCH v2, part3 00/12] accurately calculate zone->managed_pages
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
https://git.kernel.org/pub/scm/linux/kernel/git/mhocko/mm.git since-3.8
Patch 1-6 are minor fixes and furthur work for preview patchset,
which uses common helper functions to free reserved pages.
Patch 7-11 enhance the way to calculate zone->managed_pages and report
available pages as "MemTotal" for each NUMA node
Patch 12 concentrates adjusting of totalram_pages, which reduces 37
references to totalram_pages from arch/ subdirectories.
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!
There is still another part still under development:
Part4: introduce helper functions to simplify mem_init() and remove the
global variable num_physpages.
Jiang Liu (12):
mm: enhance free_reserved_area() to support poisoning memory with
zero
mm/ARM64: kill poison_init_mem()
mm/x86: use common help functions to furthur simplify code
mm/tile: use common help functions to free reserved pages
mm/powertv: use common help functions to free reserved pages
mm/acornfb: use common help functions to free reserved pages
mm: accurately calculate zone->managed_pages for highmem zones
mm: use a dedicated lock to protect totalram_pages and
zone->managed_pages
mm: avoid using __free_pages_bootmem() at runtime
mm: correctly update zone->mamaged_pages
mm: report available pages as "MemTotal" for each NUMA node
mm: concentrate adjusting of totalram_pages
