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.
This patch series adds a new interface to access the global kmsg_redirect variable by a function to be able to use it in code where CONFIG_VT_CONSOLE is not set (kernel/panic.c).
