The problem is that FRV's call into its gdbstub appears to return (if the function is marked noreturn, then the compiler is under no obligation to pass it a return address, and so GDB won't know where the bug happened). To get around this, we make the do...while wrapper in _debug_bug_trap() an endless loop from which there's no escape.

It seems nothing has included the frv asm/init.h header for some time, and its actual contents are out of date with include/linux/init.h. So just delete it.

FRV is placing some code in the .text.init section but does not reference that section in its linker scripts. This change moves this code from the .text.init section to the .init.text section, which is presumably where it belongs.
