- Added support for crash dumps:-

Browse source 
* Recognize the option /CRASHDUMP on the kernel command line to specify
the type of dump desired.
* Added a new driver (diskdump) which wraps the miniport for the disk
containing the pagefile and does the crash dump i/o.
* Added a FSCTL to get the mapping between LCNs and disk offsets so
crash dumps don't need to go through the filesystem.
