These warnings are showed by scripts/mod/modposts.c. It checks section mismatch stricter than before. Some of them are not defined as __init even if it's called at just boottime. This is simple to fix. Second case is that the functions judge which functions should call (boottime or normal) by themselves. pte_alloc_one_kernel() looks its case. In this case, they must be registered in whitelist of modpost.c Other possibility is they are just rare called functions. It should be investigated....
