Hi Ziqi,

The lockdep warning remains a problem that impacts the 
functionality of lockdep. Furthermore, the lockdep issue
is consistently reproducible, unlike the stuck/crash issue,
which is rare and only occurred after the clock scale code 
had been in use for several years.

Therefore, I recommend ACK reverting first and then merging 
the fixed patch together.

Thanks.
Peter
