Since most of your CPU utilization is interrupt CPU, your router just might have hit it's capacity limits. What's your aggregate bps through the router at the same time?

What do you mean by aggregate bps ?

Hello Sanjaya,
please post the show interface summary output
Harish.

Thank you Harish, please find the output
show interface summary
*: interface is up
IHQ: pkts in input hold queue IQD: pkts dropped from input queue
OHQ: pkts in output hold queue OQD: pkts dropped from output queue
RXBS: rx rate (bits/sec) RXPS: rx rate (pkts/sec)
TXBS: tx rate (bits/sec) TXPS: tx rate (pkts/sec)
TRTL: throttle count

Assuming those bit rates correspond to your high CPU usage, what might be happening is packet fragmentation across your tunnel interface.
Have you implemented Cisco recommendation to avoid such fragmentation? I.e.: http://www.cisco.com/c/en/us/support/docs/ip/generic-routing-encapsulation-gre/25885-pmtud-ipfrag.html?referring_site=smartnavRD
