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.

WARNING: modpost: vmlinux.o(.text.unlikely+0x2bc): Section mismatch in reference from the function early_init_mmu() to the function .init.text:hash__early_init_mmu()
The function early_init_mmu() references
the function __init hash__early_init_mmu().
This is often because early_init_mmu lacks a __init 
annotation or the annotation of hash__early_init_mmu is wrong.
