The bulk of the changes are the s390 merge bits, but there are small 
details like fixing some races in the new unplugging code etc, more 
driverfs, USB, framebuffer updates etc.

The most noticeable changes (and that people will probably find some 
nagging missing things with) are the header file cleanups - expect some 
missing headers here and there - and the kernel build changes. Different 
dependency stuff etc.
