addr2line

[Paul Koning <pkoning at equallogic dot com>]

Is there a version of binutils where addr2line works for MIPS kernel
addresses?  Ever since GDB changed to Dwarf-2 output, addr2line hasn't
worked for addresses in the kernel range.

With older kernels (Stabs format) supplying sign-extended 64 bit
addresses works, though it's not really reasonable to have to do
that.  But with Dwarf binaries neither form works:
