I'll upload the .config once I've logged the bug; need to check how to generate the preprocessed source for you.

This affects vesion 13.09, had expected to get the opportunity to flag that during reporting.

Reverting commit 5ecaba3d9f4ab514fe8d383534e24b306f116896 in the above tree avoids triggering the issue.

Can you please attach preprocessed source with the command line to reproduce the failure. For the compile that fails repeat it with '-save-temps' added to the GCC command line. This will cause the compiler to output a *.i file - this is what should be attached.

Like I said I'm looking at that (but prioritising trying to work around the bug).

Replacing all uses of __smp_call_func_t with void * seems to resolve the issue for me.

Can you also provide the command line you used?

The command from the original report:

make C=1 -j4 ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- uImage dtbs

gives:
