Bisected 3.9-rc1 boot failure on G5

Hi,

Booting 3.9-rc1 fails with the following dump:

   Invalid memory access at %SSR0: 00000000.00000380 %SSR1: 90000000.00081000

According to bisect, it's caused by 1fbe9cf2598dae3bd464d860bd89c67b1ff8682b
(powerpc: Build kernel with -mcmodel=medium).

I'm loading & booting the kernel with GRUB 2.00 on iMac G5 (PowerMac8,1),
toolchain is GCC 4.7.2 / binutils 2.23.1.
