In linux kernel since version 5.2 (release Date: 2019-07-07)
This option enables -fsanitize=integer-divide-by-zero which checks
for integer division by zero. This is effectively redundant with the
kernel's existing exception handling, though it can provide greater
debugging information under CONFIG_UBSAN_REPORT_FULL.
