[Crash-utility] [PATCH] take Hardware Error & kernel pointer bug as separate panicmsg

[drc at yahoo-inc.com]

There are just too many kinds of panic types are categorized under
the same Oops: xxxx, this is really ambiguous and makes it not so useful

       PANIC: "Oops: 0000 [#1] SMP " (check log for details)

this patch separated two kinds out, as two most happening cases
among the machines managed by me; the match string are copied
from kernel source code exactly, after applied, I got panicmsg like:

 include/linux/kernel.h:#define HW_ERR
          panicmsg: "[Hardware Error]: CPU 7: Machine Check Exception: 5 Bank 11: f200003f000100b2"
 arch/x86/mm/fault.c:show_fault_oops
          panicmsg: "BUG: unable to handle kernel paging request at 00001248a68eb328"
