* Revision 1.1.1.1 1998/03/07 02:25:45 wsanchez
* Import of OSF Mach kernel (~mburg)
*
* Revision 1.2.16.4 1996/01/09 19:21:29 devrcs
* Added bootstrap map for alpha.
* This probably should be moved to some MD include file.

* way of doing things.
* [1995/12/01 19:49:04 jfraser]
*
* Merged '64-bit safe' changes from DEC alpha port.

* Revision 1.2.16.3 1995/01/06 19:50:04 devrcs
* mk6 CR668 - 1.3b26 merge
* Added region_desc structure;

* text and data sizes are set to include the entire

*
* The rest of the file sits where the kernel BSS
* should be. A boot_info record describes the
* sizes of the next 3 sections. Following this
* are the kernel symbol table, the bootstrap image
* (including its symbol table), and the loader
* information for the bootstrap image. Each
* of these sections is padded to an integer (4-byte)
* boundary.
*
* When the file is loaded into memory, the kernel
* text and data segments are at their normal locations.
*
* The boot_info structure appears at the start of
* the bss (at 'edata[]'):
