powerpc allmodconfig build broken due to commit 15863ff3b (powerpc: Make chip-id information available to userspace)

[Guenter Roeck]

Hi all,

powerpc allmodconfig build on the latest upstream kernel results in:

ERROR: ".cpu_to_chip_id" [drivers/block/mtip32xx/mtip32xx.ko] undefined!

This is due to commit 15863ff3b (powerpc: Make chip-id information available to userspace).
Not surprising, as cpu_to_chip_id() is not exported.

Reverting this commit fixes the problem. Any good idea how to fix it for real ?
