m68k: kernel/up.c:16: error: dereferencing pointer to incomplete type

m68k: kernel/up.c:16: error: dereferencing pointer to incomplete type

[Geert Uytterhoeven]

Hi Stephen,

I can't seem to reproduce the compile failure of kernel/up.c on m68k,
as shown on
http://kisskb.ellerman.id.au/kisskb/buildresult/186066/:

| kernel/up.c:16: error: dereferencing pointer to incomplete type

I am using the exact same version (ebdcc81c71937b30e09110c02a1e8a21fa770b6f).
I'm using a different compiler, though (gcc 4.1.2).

If it is reproducible, can you please send me kernel/up.i?

Thanks!

Gr{oetje,eeting}s,

						Geert

When kisskb gets an error in building a kernel, it tries to bisect the
problem starting from a known good kernel.  The above error occurs
during the bisection process not when building the original kernel.  I
guess we need to be a bit more careful when reporting the errors.  Sorry
about that.

It was actually building commit
"[ad33ea3a8d2ec324dc0f46b6ae404d824d2b349b] bnx2x: Missing mask when
calculating flow control", I think.

Ah, that explains it, thanks!

I had also just noticed kernel/up.o was compiled twice, and the first
one succeeded.
Now I understand why...

This has now been fixed, thanks to Michael.

Yeah sorry that is confusing.

Should be fixed now.

I should read more email before replying to any :-)

Thanks, Michael.
