Revert "driver core: create a private portion of struct device"

2009-01-09T23:06:12+00:00

This reverts commit 2831fe6f9cc4e16c103504ee09a47a084297c0f3.

Turns out that device_initialize shouldn't fail silently.
This series needs to be reworked in order to get into proper
shape.

topology: Fix sparc64 build.

2009-01-07T23:34:47+00:00

Due to changeset ba84be2338d3a2b6020d39279335bb06fcd332e1 ("remove
linux/hardirq.h from asm-generic/local.h") the sparc64 build started
failing on drivers/base/topology.c:

  drivers/base/topology.c: In function ‘show_physical_package_id’:
  drivers/base/topology.c:103: error: implicit declaration of function ‘cpu_data’
  drivers/base/topology.c:103: error: request for member ‘proc_id’ in something not a structure or union
  drivers/base/topology.c: In function ‘show_core_id’:
  drivers/base/topology.c:106: error: request for member ‘core_id’ in something not a structure or union

Adding the obvious fix of including asm/cpudata.h into asm/topology.h on
sparc64 doesn't fix it, in fact it makes things worse because of the
header file dependency chain:

	linux/gfp.h --> linux/mmzone.h --> linux/topology.h -->
	asm/topology.h --> asm/cpudata.h --> linux/percpu.h -->
	linux/slab.h

which results in:

  include/linux/slub_def.h: In function ‘kmalloc_large’:
  include/linux/slub_def.h:209: error: implicit declaration of function ‘__get_free_pages’
  include/linux/slub_def.h:209: error: ‘__GFP_COMP’ undeclared (first use in this function)
  include/linux/slub_def.h:209: error: (Each undeclared identifier is reported only once
  include/linux/slub_def.h:209: error: for each function it appears in.)
  include/linux/slub_def.h:209: warning: cast to pointer from integer of different size

The simplest thing to do is to add yet another one-off hack like parts
of the guilty changeset did, by putting an explicit linux/hardirq.h
include into drivers/base/topology.c

mm: show node to memory section relationship with symlinks in sysfs

2009-01-06T23:59:00+00:00

Show node to memory section relationship with symlinks in sysfs

Add /sys/devices/system/node/nodeX/memoryY symlinks for all
the memory sections located on nodeX.  For example:
/sys/devices/system/node/node1/memory135 -> ../../memory/memory135
indicates that memory section 135 resides on node1.

Also revises documentation to cover this change as well as updating
Documentation/ABI/testing/sysfs-devices-memory to include descriptions
of memory hotremove files 'phys_device', 'phys_index', and 'state'
that were previously not described there.

In addition to it always being a good policy to provide users with
the maximum possible amount of physical location information for
resources that can be hot-added and/or hot-removed, the following
are some (but likely not all) of the user benefits provided by
this change.
Immediate:
  - Provides information needed to determine the specific node
    on which a defective DIMM is located.  This will reduce system
    downtime when the node or defective DIMM is swapped out.
  - Prevents unintended onlining of a memory section that was
    previously offlined due to a defective DIMM.  This could happen
    during node hot-add when the user or node hot-add assist script
    onlines _all_ offlined sections due to user or script inability
    to identify the specific memory sections located on the hot-added
    node.  The consequences of reintroducing the defective memory
    could be ugly.
  - Provides information needed to vary the amount and distribution
    of memory on specific nodes for testing or debugging purposes.
Future:
  - Will provide information needed to identify the memory
    sections that need to be offlined prior to physical removal
    of a specific node.

Symlink creation during boot was tested on 2-node x86_64, 2-node
ppc64, and 2-node ia64 systems.  Symlink creation during physical
memory hot-add tested on a 2-node x86_64 system.

driver core: add root_device_register()

2009-01-06T18:44:33+00:00

Add support for allocating root device objects which group
device objects under /sys/devices directories.

Also add a sysfs 'module' symlink which points to the owner
of the root device object. This symlink will be used in virtio
to allow userspace to determine which virtio bus implementation
a given device is associated with.

driver core:fix duplicate removing driver link in __device_release_driver

2009-01-06T18:44:33+00:00

In __device_release_driver(),driver_sysfs_remove() has removed the
driver link under device dir in sysfs, but sysfs_remove_link() is
called again to do such thing. Remove the duplicate call to
sys_remove_link().
