This part broke ppc32:
| arch/powerpc/kernel/prom.c: In function 'early_init_devtree':
| arch/powerpc/kernel/prom.c:1166: error: '__end_interrupts' undeclared (first
use in this function)
| arch/powerpc/kernel/prom.c:1166: error: (Each undeclared identifier is
reported only once
| arch/powerpc/kernel/prom.c:1166: error: for each function it appears in.)
After applying the patch below, I was able to build and boot a kernel for the
Sequoia.
