Presume that kernel is compiled for x86_64 with gcc version 13.3.0:
make allmodconfig
make KCFLAGS="-fno-inline-small-functions -fno-inline-functions-called-once"
This results a modpost warning:
WARNING: modpost: vmlinux: section mismatch in reference: xen_pgd_walk+0x42
(section: .text) -> xen_mark_pinned (section: .init.text)
As xen_pgd_walk is only referenced in xen_after_bootmem(void) which is
also in .init.text, I add __init for xen_pgd_walk to fix this issue.
