After merging the net-next tree, today's linux-next build (x86_64
allmodconfig) failed like this:

x86_64-linux-ld: unknown architecture of input file `net/bpfilter/bpfilter_umh.o' is incompatible with i386:x86-64 output

Caused by commit

  d2ba09c17a06 ("net: add skeleton of bpfilter kernel module")

In my builds, the host is PowerPC 64 LE ...

I have reverted that commit along with

  61a552eb487f ("bpfilter: fix build dependency")
  13405468f49d ("bpfilter: don't pass O_CREAT when opening console for debug")

for today.  

I am still getting this failure (well, at least yesterday I did).

Still happened today.  My guess is that bpfilter_umh needs to be built
with the kernel compiler (not the host compiler - since ir is meant to
run on the some machine as the kernel, right?) but will require the
kernel architecture libc etc


I replaced the reverts above with the following:

This does not build in a cross compile environment
