kerneloops.org has been using an improved "decodecode" script,
specifically it has a special marker that shows which line in the assembly
the oops happened at, like this:
20: 83 e0 03 and $0x3,%eax
23: 09 d8 or %ebx,%eax
25: 85 db test %ebx,%ebx
27: 89 02 mov %eax,(%edx)
29: 74 0f je 0x3a
2b:* 3b 73 04 cmp 0x4(%ebx),%esi <-- trapping instruction
2e: 75 05 jne 0x35
30: 89 53 04 mov %edx,0x4(%ebx)
33: eb 07 jmp 0x3c
35: 89 53 08 mov %edx,0x8(%ebx)
this patch updates the kernel copy to also have this functionality.
