Hi Nikhil.
Overall this series looks good. The patch specific comments, I will send
on each patches.
Please fix the
1) ./devtools/check-git-log.sh & ./devtools/checkpatches.sh issues with
series
2) I guess for next revision you could split the patches to more fine
granularity with make sure each patch build separately.
