I am getting the following warning when I build kernel 4.9-git on my PowerBook

   AS      arch/powerpc/kernel/misc_32.o
arch/powerpc/kernel/misc_32.S:299:7: warning: "CONFIG_FSL_BOOKE" is not defined 
[-Wundef]

This problem has been bisected to commit 989cea5c14be ("kbuild: prevent 
lib-ksyms.o rebuilds").

Thanks,

Hi Larry,

This is strange you've bisected it there, I can't see how that patch would
trigger it. That said, powerpc has had a few small build system glitches.

It looks like this warning could be fixed by changing #elif CONFIG_FSL_BOOKE
to #elif defined (CONFIG_FSL_BOOKE). Want to send a patch (if it works)?

Thanks,
Nick
