This commit enables the fields relating to process name and the core number the process was last scheduled. The fields will be used by keepalive monitoring framework in future commits. This commit also fixes the following "sparse" warning: lib/process.c:439:16: error: use of assignment suppression and length modifier together in gnu_scanf format [-Werror=format=].
