Refresh NODE_DATA() for generic archs. In this case, NODE_DATA(nid) == node_data[nid]. node_data[] is array of address of pgdat. So, refresh is quite simple. Signed-off-by:

For node hotplug, basically we have to allocate new pgdat. But, there are several types of implementations of pgdat. 1. Allocate only pgdat. This style allocate only pgdat area. And its address is recorded in node_data[]. It is most popular style. 2. Static array of pgdat In this case, all of pgdats are static array. Some archs use this style. 3. Allocate not only pgdat, but also per node data. To increase performance, each node has copy of some data as a per node data. So, this area must be allocated too. Ia64 is this style. Ia64 has the copies of node_data[] array on each per node data to increase performance. In this series of patches, treat (1) as generic arch. generic archs can use generic function. (2) and (3) should have its own if necessary. This patch defines pgdat allocator. Updating NODE_DATA() macro function is in other patch. Signed-off-by:

This is to find node id from acpi's handle of memory_device in DSDT. _PXM for the new node can be found by acpi_get_pxm() by using new memory's handle. So, node id can be found by pxm_to_nid_map[]. This patch becomes simpler than v2 of node hot-add patch. Because old add_memory() function doesn't have node id parameter. So, kernel must find its handle by physical address via DSDT again. But, v3 just give node id to add_memory() now. Signed-off-by:

Change the name of old add_memory() to arch_add_memory. And use node id to get pgdat for the node at NODE_DATA(). Note: Powerpc's old add_memory() is defined as __devinit. However, add_memory() is usually called only after bootup. I suppose it may be redundant. But, I'm not well known about powerpc. So, I keep it. (But, __meminit is better at least.) Signed-off-by: -

[PATCH] Catch notification of memory add event of ACPI via container driver. (avoid redundant call add_memory) When acpi_memory_device_init() is called at boottime to register struct memory acpi_memory_device, acpi_bus_add() are called via acpi_driver_attach(). But it also calls ops->start() function. It is called even if the memory blocks are initialized at early boottime. In this case add_memory() return -EEXIST, and the memory blocks becomes INVALID state even if it is normal. This is patch to avoid calling add_memory() for already available memory.

[PATCH] Catch notification of memory add event of ACPI via container driver. (register start func for memory device) This is a patch to call add_memroy() when notify reaches for new node's add event. When new node is added, notify of ACPI reaches container device which means the node. Container device driver calls acpi_bus_scan() to find and add belonging devices (which means cpu, memory and so on). Its function calls add and start function of belonging devices's driver. Howevever, current memory hotplug driver just register add function to create sysfs file for its memory. But, acpi_memory_enable_device() is not called because it is considered just the case that notify reaches memory device directly. So, if notify reaches container device nothing can call add_memory(). This is a patch to create start function which calls add_memory(). add_memory() can be called by this when notify reaches container device. [akpm@osdl.org: coding cleanups] Signed-off-by:

Current acpi memory hotplug just looks into the first entry of resources in _CRS. But, _CRS can contain plural resources. So, if _CRS contains plural resoureces, acpi memory hot add cannot add all memory. With this patch, acpi memory hotplug can deal with Memory Device, whose _CRS contains plural resources. Tested on ia64 memory hotplug test envrionment (not emulation, uses alpha version firmware which supports dynamic reconfiguration of NUMA.) Note: Microsoft's Windows Server 2003 requires big (>4G)resoureces to be divided into small (<4G) resources. looks crazy, but not invalid. (See http://www.microsoft.com/whdc/system/pnppwr/hotadd/hotaddmem.mspx) For this reason, a firmware vendor who supports Windows writes plural resources in a _CRS even if they are contiguous.

Builds on ARM report link problems with common configurations like statically linked NFS (for nfsroot). The symptom is that __init section code references __exit section code; that won't work since the exit sections are discarded (since they can never be called). The best fix for these particular cases would be an "__init_or_exit" section annotation. Signed-off-by:

This reverts commit e5c44fd8. Thanks to Daniel Ritz and Michal Piotrowski for noticing the problem. Daniel says: "[The] reason is a recent change that made modules always shows as module.mod. it breaks modprobe and probably many scripts..besides lsmod looking horrible stuff like this in modprobe.conf: install pcmcia_core /sbin/modprobe --ignore-install pcmcia_core; /sbin/modprobe pcmcia makes modprobe fork/exec endlessly calling itself...until oom interrupts it" Signed-off-by:
