Hi,

I need to JUST profile overhead associated with interprocessor 
interrupt in terms of cycles consumed in a 64-bit Linux O/S. 
Assume I have 2-cpu system. I want to know cycles consumed to 
sending IPI, flushing remote CPU TLB and finally flushing its own 
TLB. Any help is appreciated.

Thanks in advance.

Regards,
Vineet
