Re: [Crash-utility] [PATCH] ppc64: rework bt command

As an addendum to crash commit 5fe78861ea1589084f6a2956a6ff63677c9269e1, 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, Dave
