virtual kernel memory description
WDK: virtual kernel memory description.
The dxd::memory is a kernel memory representation of the kernels virtual memory description. It is an internally used wrapper to generate a virtual kernel memory representation from a platform independent pointer:size description.

IOKit memory free.
Checks the underlaying OS memory descriptor,
synchronizes and unwires it from memory and
releases the memory descriptor.

in contrast to an IOKit MemoryDescriptor MDLs do not support reference counting. take care when creating a dxd::memory from a dxd::buffer: although the dxd::memory holds an MDL to the buffer the buffer itself is not retained after the dxd::buffer is released!
