Subject[PATCH] FRV: Fix kernel configuration
Date

The attached patch fixes the FRV configuration to work with 2.6.12-rc1. It
does this by breaking out the kernel hacking menu into a separate file, in the
same way this is done in other archs.

- If you say Y here, you will have some control over the system even

- by pressing various keys while holding SysRq (Alt+PrintScreen). It
