Yes I do indeed need to build x86_64 first, then make distclean or
mrproper and then 32bit build fails

I will fix my 64 bit build soonish.
In the meantime could someone do:

1) git clean -dxf
2) Make a 64 bit x86 build.
3) make distclean
4) git ls-files -o

And post the output of 4)
Something is left that causes us to fail and I wonder what it is.

without using O=dir, correct?

Afraid not; git ls-files -o only listed the build output file for me.  Sorry.

I can't reproduce this on a 64-bit host no matter what I do.
Alan, could you please provide your 64-bit .config?
Also, I could give Sam ssh to this machine.

Hi Alan.

Can I ask you to persuade this a bit more?

1) when it fails try using "make V=1" and post the command executed.
1a) Do the same when it works and compare the two
2) try to do: make path/file.i and check if the generated .i file
   differ when it fails and when it is ok.

Other than that I have no ideas for the moment.

One additional request.
Can you check if your .config differ when it fails and when it succeeds.

[The code fails due to DECLARE_PER_CPU() does not do it's job I think].

Thanks,

I will take a serious look at it when I get time. I hit it while fighting
a pair of ATA controller problems and really I have to sort those out
before I got back and beat up the other stuff.
