I get this on an ARCH=ppc prep build:

arch/ppc/kernel/built-in.o: In function `__main':
arch/ppc/kernel/entry.S:(.text+0x2eda): undefined reference to `htab_hash_searches'
arch/ppc/kernel/entry.S:(.text+0x2ede): undefined reference to `htab_hash_searches'
arch/ppc/kernel/entry.S:(.text+0x2ee2): undefined reference to `primary_pteg_full'
arch/ppc/kernel/entry.S:(.text+0x2ee6): undefined reference to
`primary_pteg_full'

(The references are actually in arch/ppc/kernel/ppc_htab.c.)

I guess I'll cherry-pick the other commits from your tree, since I'm
making a string for Linus, unless you have a better suggestion.

Paul.
