We don't need a "default" ktype for a kset. We should set this explicitly every time for each kset. This change is needed so that we can make ksets dynamic, and cleans up one of the odd, undocumented assumption that the kset/kobject/ktype model has. This patch is based on a lot of help from Kay Sievers.

This patch reorganizes the way suspend and resume notifications are sent to drivers. The major changes are that now the PM core acquires every device semaphore before calling the methods, and calls to device_add() during suspends will fail, while calls to device_del() during suspends will block. It also provides a way to safely remove a suspended device with the help of the PM core, by using the device_pm_schedule_removal() callback introduced specifically for this purpose, and updates two drivers (msr and cpuid) that need to use it.

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. Signed-off-by: NDaniel Drake <dsd@gentoo.org> Acked-by: NRafael J.

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.

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().

We have flags to indicate whether a section actually has a valid mem_map associated with it. This is never set and we rely solely on the present bit to indicate a section is valid. By definition a section is not valid if it has no mem_map and there is a window during init where the present bit is set but there is no mem_map, during which pfn_valid() will return true incorrectly. Use the existing SECTION_HAS_MEM_MAP flag to indicate the presence of a valid mem_map. Switch valid_section{,_nr} and pfn_valid() to this bit. Add a new present_section{,_nr} and pfn_present() interfaces for those users who care to know that a section is going to be valid.
