WARNING: vmlinux.o(.text+0xb9fc): Section mismatch in reference from the function mmu_mark_initmem_nx() to the function .init.text:mmu_mapin_ram_chunk()
The function mmu_mark_initmem_nx() references
the function __init mmu_mapin_ram_chunk().
This is often because mmu_mark_initmem_nx lacks a __init 
annotation or the annotation of mmu_mapin_ram_chunk is wrong.
