Merge git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-2.6

This can be broken down into these major areas:
 - Documentation updates (language translations and fixes, as
   well as kobject and kset documenatation updates.)
 - major kset/kobject/ktype rework and fixes.  This cleans up the
   kset and kobject and ktype relationship and architecture,
   making sense of things now, and good documenation and samples
   are provided for others to use.  Also the attributes for
   kobjects are much easier to handle now.  This cleaned up a LOT
   of code all through the kernel, making kobjects easier to use
   if you want to.
 - struct bus_type has been reworked to now handle the lifetime
   rules properly, as the kobject is properly dynamic.
 - struct driver has also been reworked, and now the lifetime
   issues are resolved.
 - the block subsystem has been converted to use struct device
   now, and not "raw" kobjects.  This patch has been in the -mm
   tree for over a year now, and finally all the issues are
   worked out with it.  Older distros now properly work with new
   kernels, and no userspace updates are needed at all.
 - nozomi driver is added.  This has also been in -mm for a long
   time, and many people have asked for it to go in.  It is now
   in good enough shape to do so.
 - lots of class_device conversions to use struct device instead.
   The tree is almost all cleaned up now, only SCSI and IB is the
   remaining code to fix up...
