Updating global variable's name to follow a consistent naming convention.
Explicitly moved from __ to _ by direction of Ben Walsh
Change accomplished with the following script:
#!/bin/bash
echo "Searching for ${1} to replace with ${2}"
find ./ \( -name "*.[chs]" -o -name "sysgen.py" -o -name "*.kconf" -o -name "*.arch" \) \
! -path "./host/src/genIdt/*" \
! -path "*/outdir/*" | xargs sed -i 's/\b'${1}'\b/'${2}'/g';
