From: Randy Dunlap <rdunlap@infradead.org>
Fix the section mismatch warning in arch/x86/mm/pti.c:
WARNING: vmlinux.o(.text+0x6972a): 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. FATAL: modpost: Section mismatches detected.
Fixes: 85900ea51577 ("x86/pti: Map the vsyscall page if needed")
