Hyeonggon Yoo bf97ea76ea lib/Kconfig.debug: do not enable DEBUG_PREEMPT by default 
commit cc6003916ed46d7a67d91ee32de0f9138047d55f upstream.

In workloads where this_cpu operations are frequently performed,
enabling DEBUG_PREEMPT may result in significant increase in
runtime overhead due to frequent invocation of
__this_cpu_preempt_check() function.

This can be demonstrated through benchmarks such as hackbench where this
configuration results in a 10% reduction in performance, primarily due to
the added overhead within memcg charging path.

Therefore, do not to enable DEBUG_PREEMPT by default and make users aware
of its potential impact on performance in some workloads.
