Seems that this flags is linked to many things :) I tried removing PPC_PREP
bool but the kernel fail to compile with again new errors :

arch/ppc/kernel/built-in.o(.init.text+0x610): In function `DoSyscall':
arch/ppc/kernel/entry.S: undefined reference to `prep_init'

arch/ppc/platforms/built-in.o(.pmac.text+0x936): In function 
'note_bootable_part':
: undefined reference to `boot_dev'

I attach my config, someone asked me for that previously but
i crashed my system since, thus here it is.
