Driver Core update for 2.6.4

Hi,

Here are a few driver core changes for 2.6.3.  They have all been in the -mm
tree with the exception of the kref patch, which has been reviewed on lkml.
These patches add a few more sysfs class entries, clean up the cdev interface
and add the kref structure.

Please pull from:
	bk://kernel.bkbits.net/gregkh/linux/driver-2.6

thanks,

greg k-h

p.s. I'll send these as patches in response to this email to lkml for
those who want to see them.
