1543ecae88 Changed the way that the exec image header is read to be filesystem- 
centric rather than VM-centric to fix a problem with errors not being
detectable when the header is read.
Killed exech_map as a result of these changes.
There appears to be no performance difference with this change.

51253b5e70 Improved CPU identification and initialization routines. This 
supports All Cyrix CPUs, IBM Blue Lightning CPU and NexGen (now AMD)
Nx586 CPU, and initialize special registers of Cyrix CPU and msr of
IBM Blue Lightning CPU.

If revision of Cyrix 6x86 CPU < 2.7, CPU cache is enabled in
write-through mode.  This can be disabled by kernel configuration
options.

eb0ff1925c Re-construct PC-98 code of device_infor[] entries. Enabled all

808a36ef65 Make the long-awaited change from $Id$ to $FreeBSD$ 
This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.

Boy, I'm glad we're not using sup anymore.  This update would have been
insane otherwise.

28348225e5 Change initialize routine of Cyrix 5x86 CPU. 
- Turn off BTB (Branch Target Buffer) because the BTB makes system
  unstable on some machines. The BTB feature can be enabled if
  "options BTB_EN" is added in kernel a configuration file.
- Change comment.
- Reorder `orb XX,%al's.
- Reset NMI F/F (mask NMI) before setting registers, and set it after
  setting them. Normally, this change has no effect.
