WARNING: vmlinux.o(.text+0x39e3e): Section mismatch in reference from the function pti_clone_pgtable() to the function .init.text:pti_user_pagetable_walk_pte()
The function pti_clone_pgtable() references
the function __init pti_user_pagetable_walk_pte().
This is often because pti_clone_pgtable lacks a __init 
annotation or the annotation of pti_user_pagetable_walk_pte is wrong.
