create /sys/.../power when CONFIG_PM is set

2007-11-28T21:53:53+00:00

The CONFIG_SUSPEND changes in 2.6.23 caused a regression under certain
configuration conditions (SUSPEND=n, USB_AUTOSUSPEND=y) where all USB
device attributes in sysfs (idVendor, idProduct, ...) silently disappeared,
causing udev breakage and more.

The cause of this is that the /sys/.../power subdirectory is now only
created when CONFIG_PM_SLEEP is set, however, it should be created whenever
CONFIG_PM is set to handle the above situation.  The following patch fixes
the regression.

cleanup asm/scatterlist.h includes

2007-11-02T07:47:06+00:00

Not architecture specific code should not #include .

This patch therefore either replaces them with
#include  or simply removes them if they were
unused.

Revert "Driver core: remove class_device_*_bin_file"

2007-10-31T19:51:29+00:00

This reverts commit fcd239d3d5575e5cc63aab5c33cf6dc66904f6d6.

I messed up, ia64 still uses these files in the current tree, and now
can not build the pci code, which all ia64 boxes seem to require :)

This fixes that mistake.

Driver Core: fix bug in device_rename() for SYSFS_DEPRECATED=y

2007-10-31T04:52:33+00:00

This should fix the sysfs warnings that renaming network devices is
causing to show up with CONFIG_SYSFS_DEPRECATED=y

The code just shouldn't run if class devices are real directories, it's
an update for the symlink in the class directory. Nobody noticed that as
long as the creation of sysfs files silently failed, and we both missed
it before the merge, because we don't run SYSFS_DEPRECATED=y.

Driver core: remove class_device_*_bin_file

2007-10-31T04:52:33+00:00

These functions are not used by anyone, so remove them from the tree.

The class_device code will be removed soon anyway, so no future users
will ever be possible.

memory hotplug: rearrange memory hotplug notifier

2007-10-22T15:13:17+00:00

Current memory notifier has some defects yet.  (Fortunately, nothing uses
it.) This patch is to fix and rearrange for them.

  - Add information of start_pfn, nr_pages, and node id if node status is
    changes from/to memoryless node for callback functions.
    Callbacks can't do anything without those information.
  - Add notification going-online status.
    It is necessary for creating per node structure before the node's
    pages are available.
  - Move GOING_OFFLINE status notification after page isolation.
    It is good place for return memory like cache for callback,
    because returned page is not used again.
  - Make CANCEL events for rollingback when error occurs.
  - Delete MEM_MAPPING_INVALID notification. It will be not used.
  - Fix compile error of (un)register_memory_notifier().

cpu hotplug: topology: remove topology_dev_map

2007-10-18T21:37:21+00:00

By previous cpu hotplug notifier change, we don't need to track topology_dev
existence for each cpu by topology_dev_map.

pm_trace displays the wrong time from the RTC

2007-10-18T21:37:19+00:00

The way in which read_magic_time() displays the date read from the RTC is
apparently confusing to the users (cf.
https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=250238).  Make it
print dates in the standard way.
