Merge git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core-2.6
* git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core-2.6: (79 commits) arm: bus_id -> dev_name() and dev_set_name() conversions sparc64: fix up bus_id changes in sparc core code 3c59x: handle pci_name() being const MTD: handle pci_name() being const HP iLO driver sysdev: Convert the x86 mce tolerant sysdev attribute to generic attribute sysdev: Add utility functions for simple int/ulong variable sysdev attributes sysdev: Pass the attribute to the low level sysdev show/store function driver core: Suppress sysfs warnings for device_rename(). kobject: Transmit return value of call_usermodehelper() to caller sysfs-rules.txt: reword API stability statement debugfs: Implement debugfs_remove_recursive() HOWTO: change email addresses of James in HOWTO always enable FW_LOADER unless EMBEDDED=y uio-howto.tmpl: use unique output names uio-howto.tmpl: use standard copyright/legal markings sysfs: don't call notify_change sysdev: fix debugging statements in registration code. kobject: should use kobject_put() in kset-example kobject: reorder kobject to save space on 64 bit builds ...
