The following series mostly contains fixes to improve kdump behavior
and esp. to make older controllers which cannot be hard reset work by
doing a soft reset instead. There are a few patches factoring out
various functionality into individual functions make way for the soft
reset functionality. There is also a bugfix which prevents PCI write
combining from potentially causing commands to get lost.
