Hi all,

After merging the powerpc tree, today's linux-next build (powerpc
ppc44x_defconfig) failed like this:

make[3]: *** No rule to make target 'arch/powerpc/boot/treeImage.ebony', needed by 'arch/powerpc/boot/zImage'. Stop.
make[2]: *** [/home/sfr/next/next/arch/powerpc/Makefile:236: zImage] Error 2
make[1]: *** [/home/sfr/next/next/Makefile:224: __sub-make] Error 2
make: *** [Makefile:224: __sub-make] Error 2

It is not obvious to me what change caused this, so I have just left
the build broken for today.


Bisected to commit e6abfb536d16 ("kbuild: split device tree build rules into scripts/Makefile.dtbs")

Thanks for that.

I squashed the following fix. Hopefully, it will be ok tomorrow.

The build of ppc44x_defconfig is ok with this change
