Gunter reports problems with the corenet64_smp_defconfig:

In file included from arch/powerpc/kernel/ppc_ksyms.c:10:0: arch/powerpc/include/asm/book3s/64/kup-radix.h:11:29: error: redefinition of ‘allow_user_access’ static __always_inline void allow_user_access(void __user *to, const void __user *from, ^~~~~~~~~~~~~~~~~ In file included from arch/powerpc/include/asm/uaccess.h:12:0, from arch/powerpc/kernel/ppc_ksyms.c:8: arch/powerpc/include/asm/kup.h:12:20: note: previous definition of ‘allow_user_access’ was here static inline void allow_user_access(void __user *to, const void __user *from, ^~~~~~~~~~~~~~~~~

This is because ppc_ksyms.c imports asm/book3s/64/kup-radix.h guarded by CONFIG_PPC64, rather than CONFIG_PPC_BOOK3S_64 which it should do.

Fix it.
