 As an addendum to crash commit

 this patch for the ppc64 "bt" command prevents an invalid error message
 from being displayed when an active non-panic task is interrupted while
 running in user space.  Without the patch, the command correctly indicates
 "Task is running in user space", dumps the user-space exception frame, but
 then prints the invalid error message "bt: invalid kernel virtual address:
 ffffffffffffff90 type: Regs NIP value".
 The patch has been ACK'd offline by Hari Bathini.
 Thanks,
