When implementing movablemem_map boot option, we introduced an array
movablemem_map.map[] to store the memory ranges to be set as ZONE_MOVABLE.
Since ZONE_MOVABLE is the latst zone of a node, if user didn't specify
the whole node memory range, we need to extend it to the node end so that

As mentioned by Liu Jiang and Wu Jiangguo, users could specify DMA,

If kernelcore or movablecore is specified at the same time with

Hi Yinghai, all,
As Yinghai have implemented parsing numa info early more considerately,

This patch-set is based on Linux 3.9 rc-2, but need to apply Yinghai's

Please refer to:
Since node info in SRAT may not be in increasing order, we may meet
a lower range after we handled a higher range. So we need to keep
the lowest movable pfn each time we parse a SRAT memory entry, and
update it when we get a lower one.
This patch introduces a new array zone_movable_limit[], which

Currently lock_memory_hotplug()/unlock_memory_hotplug() are used to
protect totalram_pages and zone-managed_pages. Other than the memory
hotplug driver, totalram_pages and zone-managed_pages may be modified
by Xen balloon, virtio_balloon etc at runtime. For those case, memory
hotplug lock is a
Commit mm: introduce new field 'managed_pages' to struct zone assumes
that all highmem pages will be freed into the buddy system by function
mem_init(). But that's not always true, some architectures may reserve
some highmem pages during boot. For example PPC may allocate highmem
pages for giagant
Avoid using __free_pages_bootmem() at runtime, so we could easily
manage totalram_pages and zone-managed_pages. With this change applied,
__free_pages_bootmem() is only used by bootmem.c and nobootmem.c at
boot time, so mark it as __init. And other callers of
__free_pages_bootmem() have been
Enhance adjust_managed_page_count() to adjust totalhigh_pages for
highmem pages. And change code which directly adjusts totalram_pages
to use adjust_managed_page_count() because it adjusts totalram_pages,
totalhigh_pages and zone-managed_pages altogether in a safe way.

MemTotal from /proc/meminfo means memory pages managed by the buddy

means phsical pages present (present_pages) within the NUMA node.

Concentrate code to modify totalram_pages into the mm core, so the arch
memory initialized code doesn't need to take care of it. With these
changes applied, only following functions from mm core modify global
variable totalram_pages:
