Huh an Application can map the data it needs from a physical device using
TransBusAddrToVirtual() (which internally calls MmMapIoSpace(), which
internally calls VirtualAlloc/VirtualCopy) There is no direct way for a
driver to allocate memory on behalf of an application that the application
can then use. The expectation is that the application allocates it's own
buffer and provides that to the driver. It's really an arbitrary choice
and CE does it one way other systems may do the same or may do the opposite.
