Removed a load of unnecessary includes.
Removed unnecessary prototypes and variables.
Removed dead variables debug_flags and cpu_cache.
Removed some unnecessary cache syncs.

a change marked XXX, where gcc -Wall pointed out a bit of the original
code that looked wrong. The jury's still out on whether or not it was

http://www.research.digital.com/SRC/iag . Some of this code (badly)
needs to be cleaned up, and as-is it doesn't compile. However, getting
it in the tree is a start.
