[POWERPC] Fix powermac late initcall to only run on powermac
Current ppc64_defconfig kernel fails to boot on iSeries, dying with: Unable to handle kernel paging request for data at address 0x00000000 Faulting instruction address: 0xc00000000071b258 Oops: Kernel access of bad area, sig: 11 [#1] SMP NR_CPUS=32 iSeries <snip> NIP [c00000000071b258] .iSeries_src_init+0x34/0x64 LR [c000000000701bb4] .kernel_init+0x1fc/0x3bc Call Trace: [c000000007d0be30] [0000000000008000] 0x8000 (unreliable) [c000000007d0bea0] [c000000000701bb4] .kernel_init+0x1fc/0x3bc [c000000007d0bf90] [c0000000000262d4] .kernel_thread+0x4c/0x68 Instruction dump: e922cba8 3880ffff 78840420 f8010010 f821ff91 60000000 e8090000 78095fe3 4182002c e922cb58 e862cbb0 e9290140 <e8090000> f8410028 7c0903a6 e9690010 Kernel panic - not syncing: Attempted to kill init! This happens because some powermac code unconditionally sets ppc_md.progress to NULL. This patch makes sure the powermac late initcall is only run on powermac machines.
