[Barisa Kisku]

Hi,

What is difference between interrupt context and process
context.Fromhardware(register context) view
how they are different.In linux-2.6 interrupt stack is separate from kernel
stack.How interrupt stack pointer
is retrieved?How is the implementation in freescale ppc/powerpc.

please comment.

thanks in advance.
