[ Upstream commit ff924c5a1ec7548825cc2d07980b03be4224ffac ]
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")
