Define a new kernel dump "architecture", TEXTDUMPMAGIC, which is used

Browse Source 
to identify textdumps in the swap/dump partition.  While textdumps
aren't really an architecture, they are architecture-neutral and so
don't really correspond to any existing architecture.

Define a version number for textdumps, KERNELDUMP_TEXT_VERSION, of 1.
