I'm geting the stack pointer in the kernel, and unwind the stack till it's 
empty or  I get the program text
and report the PC. The thing is I should be able to report the correct PC, 
for a perticular sys call, in a program. But I'm missing out something in 
this, which is my concern. Any pointer on that will
simply be great.

My requirement is in the kernel space. I will use the derived PC to be used 
in the other part of the
KLM. So doing it from user space is not the idea.
