From: Alexander Duyck
Introduce a new iterator for_each_free_mem_pfn_range_in_zone.
This iterator will take care of making sure a given memory range provided
is in fact contained within a zone. It takes are of all the bounds checking
we were doing in deferred_grow_zone, and deferred_init_memmap
From: Alexander Duyck
Use the same approach that was already in use on Sparc on all the
architectures that support a 64b long.
This is mostly motivated by the fact that 7 to 10 store/move instructions
are likely always going to be faster than having to call into a function
NR_PAGES patch to stop on section aligned boundaries
Dropped patches 5-7
Will follow-up later with reserved bit rework before resubmitting
---
Alexander Duyck (4):
mm: Use mm_zero_struct_page from SPARC on all 64b architectures
mm: Drop meminit_pfn_in_nid as it is redundant
From: Alexander Duyck
As best as I can tell the meminit_pfn_in_nid call is completely redundant.
The deferred memory initialization is already making use of
for_each_free_mem_range which in turn will call into __next_mem_range which
will only return a memory range if it matches the node ID
From: Alexander Duyck
Add yet another iterator, for_each_free_mem_range_in_zone_from, and then
use it to support initializing and freeing pages in groups no larger than
MAX_ORDER_NR_PAGES. By doing this we can greatly improve the cache locality
of the pages while we do several loops over them

By guaranteeing NUMA locality I see an improvement of as high as 25% for
per-node init of a system with 12TB of persistent memory.

significant impact as initialing 3TB on remote node can take up to 39
seconds while initialing it on a local node only takes 23 seconds. It is

As we are only using the first CPU to represent the NUMA node for now I am
limiting the scope of the function so that it can only be used with unbound

than NUMA_NO_NODE.
The main motivation behind this is to address the need to be able to
schedule device specific init work on specific NUMA nodes in order to
improve performance of memory initialization.
