I ran the 32 bit and 64 bit versions in a loop for good amount of time and
captured oprofile report for vmlinux after each run. For the 32 bit runs the
top 5 are - (Also attached are complete reports after 32 bit and 64 bit runs)

samples % symbol name
20820 11.5424 copy_user_generic_c
12990 7.2015 ia32_syscall
10131 5.6165 gs_change
9053 5.0189 __dequeue_signal
7494 4.1546 find_pid

For the 64 bit run top 5 are -
samples % symbol name
10604 8.1075 system_call
8497 6.4965 __switch_to
8041 6.1479 do_signal
7712 5.8963 schedule
6538 4.9987 __dequeue_signal

I am yet to interpret/analyze the above...
