Package: linux-source-3.16
Version: 3.16.7-ckt25-1~bpo70+1

Between 3.16.7-ctk20 and 3.16.7-ctk25 the kexec functionality of the
Linux kernel was damaged.  The system I'm looking at uses a 3.3 kernel
to load the "real" kernel off a filesystem and kexec into that.  The 3.3
kernel was able to successfully kexec into a 3.16.7-ctk20 kernel, but
is unable to kexec into a 3.16.7-ctk25 kernel.  However I found the
3.16.7-ctk20 IS able to successfully kexec the 3.16.7-ctk25 kernel.

Doing a double-kexec does work around the issue, but it means I need to
hold onto that one magic kernel for the moment...

In other news, it appears sometime between 3.3 and 3.10 there started
being a requirement for GCC 4.8 on mipsel.
