The kdump data stream is an unaligned data stream for stat and
sockaddr structures.  As such, we have top copy the data structure
into a local buffer before we can reference it, otherwise we have
unaligned references (these are fixed up automatically on some CPUs,
but not on others).  We do this unconditionally to make the code
easier to read and understand.
