Yonattan Louise 9bbb6e1e7b Rename K_Task to _k_current_task
Updating global variable's name to follow a consistent naming convention.

Change accomplished with the following script:

   #!/bin/bash
   echo "Searching for ${1} to replace with ${2}"
   find ./ \( -name "*.[chs]" -o -name "sysgen.py" -o -name "*.kconf" \) \
            ! -path "./host/src/genIdt/*" \
            ! -path "*/outdir/*" | xargs sed -i 's/\b'${1}'\b/'${2}'/g';
