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.
