Enable the kernel to detect "hung tasks",
which are bugs that cause the task to be stuck in
uninterruptible "D" state indefinitiley.
Note we're setting HUNG_TASK_TIMEOUT to 10 seconds instead of
default 120 to shorten time required for detection of hung task,
as it set in axs101, axs103 and axs103_smp boards defconfigs.
