Tried to minimize actual code modifcations but we got - several comments/printf messages edited to meet line limits - occasionally switch some lines to put declarations or printfs in blocks - couple more places marked TODO or FIXME to avoid non-trivial changes - fixed PAGE_SIZE define in helpers.h to avoid redeclaration warning - remove several chunks of dead or commented code Co-authored-by: Steffen Schulz <steffen.schulz@intel.com>
