Please build with CONFIG_DEBUG_SECTION_MISMATCH=y.
It might be because I'm using your v32 patchset, hacked late at night
to apply to a 4.9 kernel, but I see this:
WARNING: vmlinux.o(.text+0x10240): Section mismatch in reference from the function arch_kexec_protect_crashkres() to the function .init.text:create_pgd_mapping()
The function arch_kexec_protect_crashkres() references
the function __init create_pgd_mapping().
This is often because arch_kexec_protect_crashkres lacks a __init?
annotation or the annotation of create_pgd_mapping is wrong.
WARNING: vmlinux.o(.text+0x102b0): Section mismatch in reference from the function arch_kexec_unprotect_crashkres() to the function .init.text:create_pgd_mapping()
The function arch_kexec_unprotect_crashkres() references
the function __init create_pgd_mapping().
This is often because arch_kexec_unprotect_crashkres lacks a __init?
