powerpc/83xx: handle machine check caused by watchdog timer
[ Upstream commit 0deae39cec6dab3a66794f3e9e83ca4dc30080f1 ]
When the watchdog timer is set in interrupt mode, it causes a
machine check when it times out. The purpose of this mode is to
ease debugging, not to crash the kernel and reboot the machine.
This patch implements a special handling for that, in order to not
crash the kernel if the watchdog times out while in interrupt or
within the idle task.
