More Driver Core patches for 2.6.10-rc1

Hi,

Here are some more driver core and sysfs fixes for 2.6.10-rc1.  They fix
a number of little bugs that people have been reporting over the past
week with the recent sysfs changes, and also the kevent changes.  The
kevent stuff also now has a proper MAINTAINERS entry, and we now export
a few more environment variables through the hotplug interface to make
userspace programs have an easier time trying to figure out how to deal
with devices properly.

Please pull from:

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.
