Maybe we can use the two registers in the Exception IPC as Pagefault IPC

	In the present implementation of exception ipc the two registers are not used 
but only given with 0. It seems a little bit waste. I mean in the page fault 
ipc the two registers include address where page fault occurs and instruction 
pointer which causes the page fault. Can we make exception ipc includes two 
registers with the next/current eip and esp?  It seems not to be bad for this 
system call because it is a little bit strange that this exception ipc doesn't 
includes anything useful.
