[PATCH 2/2] Always print panic message on current console

[Bernhard Walle]

The kernel offers with TIOCL_GETKMSGREDIRECT ioctl() the possibility to
redirect the kernel messages to a specific console.

However, since it's not possible to switch to the kernel message console after
a panic(), it would be nice if the kernel would print the panic message on the
current console.
