[PATCH] memory hotadd: pgdat->node_present_pages fix

2006-03-10T03:47:38Z

When pages are onlined, not only zone->present_pages but also pgdat->node_present_pages should be refreshed. This parameter is used to show information at /sys/device/system/node/nodeX/meminfo via si_meminfo_node(). So, it shows strange value for MemUsed which is calculated (node_present_pages - all zones free pages).

[PATCH] memhotplug: __add_section remove unused pgdat definition

2006-01-06T16:33:21Z

__add_section defines an unused pointer to the zones pgdat. Remove this definition. This fixes a compile warning. Signed-off-by: Andy Whitcroft Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[PATCH] Fix calculation of grow_pgdat_span() in mm/memory_hotplug.c

2005-12-14T05:18:16Z

The calculation for node_spanned_pages at grow_pgdat_span() is clearly wrong. This is patch for it. (Please see grow_zone_span() to compare. It is correct.) Signed-off-by: Yasunori Goto Acked-by: Dave Hansen Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[PATCH] memory hotplug: call setup_per_zone_pages_min after hotplug

2005-10-30T04:40:44Z

From: IWAMOTO Toshihiro > I found the tests does not work well with Dave's patchset. > I've found the followings: > > - setup_per_zone_pages_min() calls should be added in > capture_page_range() and online_pages() > - lru_add_drain() should be called before try_to_migrate_pages() The following patch deals with the first item.

[PATCH] memory hotplug: move section_mem_map alloc to sparse.c

2005-10-30T04:40:44Z

This basically keeps up from having to extern __kmalloc_section_memmap(). The vaddr_in_vmalloc_area() helper could go in a vmalloc header, but that header gets hard to work with, because it needs some arch-specific macros. Just stick it in here for now, instead of creating another header.

[PATCH] memory hotplug: sysfs and add/remove functions

2005-10-30T04:40:44Z

This adds generic memory add/remove and supporting functions for memory hotplug into a new file as well as a memory hotplug kernel config option. Individual architecture patches will follow. For now, disable memory hotplug when swsusp is enabled. There's a lot of churn there right now. We'll fix it up properly once it calms down.
