The "Lazy interrupt disabling for 64-bit machines" patch (which is in -rc2-mm2 through git-powerpc) seems to make -rc2-mm2 not build for ppc32 when KEXEC is enabled. Building with kexec enabled worked in -rc2-mm1.
Building -mm2 fails when trying to make the vmlinux. I don't have the exact messages anymore, sorry, but it was an "undefined reference to hard_irq_disable' in arch/powerpc/kernel/entry_32.S". This appears to be the result of an earlier warning about an "implicit declaration of hard_irq_disable" in arch/powerpc/kernel/crash.c .
(There's a comment at the top of that file that made it sound to me like the file is for PPC64 only, but looking closer makes me think that's not the case.)
Backing out that "lazy interrupt" patch got -mm2 building again. Turning kexec off works too.
I don't use kexec, I just have it config'd on. I doubt anyone is actually using kexec in -mm on ppc32. I'm just sayin'.
