Subject: Part 14 of 22 /boot,/mdec,[T]MSCP updates
Index:	/sys/<many>, /usr/src/etc/<several> 2.11BSD

Description:
Repeat-By:
Fix:
	See part 0 (the README) for the Description, the Reason and
	the instructions on how update your system.

This is part 14 of 22

The [T]MSCP arena is added in to the estimated system memory 
requirements.  The memory requirements calculation was overflowing
due to 'long' vs. 'int' problems, resulting in megabyte size estimates 
for the system - this was fixed.
