Merge git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-2.6
* git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-2.6: (36 commits) SCSI: convert struct class_device to struct device DRM: remove unused dev_class IB: rename "dev" to "srp_dev" in srp_host structure IB: convert struct class_device to struct device memstick: convert struct class_device to struct device driver core: replace remaining __FUNCTION__ occurrences sysfs: refill attribute buffer when reading from offset 0 PM: Remove destroy_suspended_device() Firmware: add iSCSI iBFT Support PM: Remove legacy PM (fix) Kobject: Replace list_for_each() with list_for_each_entry(). SYSFS: Explicitly include required header file slab.h. Driver core: make device_is_registered() work for class devices PM: Convert wakeup flag accessors to inline functions PM: Make wakeup flags available whenever CONFIG_PM is set PM: Fix misuse of wakeup flag accessors in serial core Driver core: Call device_pm_add() after bus_add_device() in device_add() PM: Handle device registrations during suspend/resume block: send disk "change" event for rescan_partitions() sysdev: detect multiple driver registrations ... Fixed trivial conflict in include/linux/memory.h due to semaphore header file change (made irrelevant by the change to mutex).
