#        vmalloc, pagealloc, migration, thp, ksm, madvise, virtio,
#        userfaultfd, memory-hotplug, shmem, rmap, zswap, zsmalloc, cleanups)
#     
#      - various other subsystems (procfs, misc, MAINTAINERS, bitops, lib,
#        checkpatch, epoll, binfmt, kallsyms, reiserfs, kmod, gcov, kconfig,
#        ubsan, fault-injection, ipc)

WARNING: modpost: vmlinux.o(.text.unlikely+0x2b0): Section mismatch in reference from the function early_init_mmu() to the function .init.text:radix__early_init_mmu()
The function early_init_mmu() references
the function __init radix__early_init_mmu().
This is often because early_init_mmu lacks a __init 
annotation or the annotation of radix__early_init_mmu is wrong.

This is often because early_init_mmu lacks a __init 
annotation or the annotation of hash__early_init_mmu is wrong.
