I applied this series ... and everything built cleanly. But when I
try to boot my Tiger (built from tiger_defconfig) it hangs quite
early in boot (last message is "Boot processor id 0x0/0xc128").
I threw some printk() into the above function, and it seems
that in the contig.c case the possible cpu map isn't initialized
early enough. The loop here just allocates mca_data for cpu 0
and no others.
