Error compiling backports-3.16-1 on a device with a 2.6.30 kernel

[Javier Casas Marin <jcasas@wifense.com>]

I am trying to compile backports-3.16-1 on a device with a 2.6.30 linux 
kernel and I get this error:
$ make
   CC [M]  /root/modules/backports-3.16-1/compat/main.o
In file included from 
/root/modules/backports-3.16-1/backport-include/linux/kernel.h:9,
                  from

                  from

                  from include/linux/prefetch.h:14,
                  from include/linux/list.h:6,

                  from 
/root/modules/backports-3.16-1/backport-include/linux/module.h:3,
                  from /root/modules/backports-3.16-1/compat/main.c:1:
/root/modules/backports-3.16-1/backport-include/linux/printk.h:5:31: 
error: linux/printk.h: No such file or directory
make[6]: *** [/root/modules/backports-3.16-1/compat/main.o] Error 1
make[5]: *** [/root/modules/backports-3.16-1/compat] Error 2
make[4]: *** [_module_/root/modules/backports-3.16-1] Error 2
make[3]: *** [modules] Error 2
make[2]: *** [modules] Error 2
make[1]: *** [modules] Error 2
make: *** [default] Error 2

it looks like I can't compile it for kernel 2.6.30 because some headers 
files are missing (printk.h was inside kernel.h in previous kernel 
versions like in 2.6.30). But the documentation says that kernels 2.6.27 
and older are supported, so what am I doing wrong?


please, I'm stuck, any hint or information will be very appreciated!

Thanks
