Joseph Koshy d0d0192f83 Correct a callchain capture bug on the i386.
On the i386 architecture, the processor only saves the current value
of `%esp' on stack if a privilege switch is necessary when entering
the interrupt handler.   Thus, `frame->tf_esp' is only valid for
an entry from user mode.  For interrupts taken in kernel mode, we
need to determine the top-of-stack for the interrupted kernel
procedure by adding the appropriate offset to the current frame
pointer.
