Subject: linux-next: build failure after merge of the pci tree (actually powerpc tree related)

Hi Ben,
After merging the pci tree, today's linux-next build (powerpc ppc64_defconfig)
failed like this:
powerpc64-linux-ld: section .text loaded at [0000000000e00000,0000000000e0721b] overlaps section .kernel:dtb loaded at [0000000000e00000,0000000000e0066f]
I have applied this patch for today (thanks to Tony Breeds and David
Gibson):

Subject: [PATCH] powerpc: do not adjust the load address for ps3
Commit c55aef0e5bc6 "powerpc/boot: Change the load address for the wrapper
to fit the kernel" adjusted the laod address if the uncompressed kernel
was too large. Ps3 does not compress the kernel and uses a different
linker script, so do not adjust the load address in that case.
fixes this build error:
powerpc64-linux-ld: section .text loaded at [0000000000e00000,0000000000e0721b] overlaps section .kernel:dtb loaded at [0000000000e00000,0000000000e0066f]
