The attached patch file contains the additional changes that I had made 
to qspinlock.c file so far. Please let me know if you or others have any 
additional feedbacks or changes that will need to go to the next version 
of the patch series.
I am going to take vacation starting from tomorrow and will be back on 
5/5 (Mon). So I will not be able to respond to emails within this period.
BTW, is there any chance that this patch can be merged to 3.16?
