Drop the __init from pcibios_map_irq() to make this section mis- match go away: WARNING: vmlinux.o(.text+0x56acd4): Section mismatch in reference from the function pcibios_scanbus() to the function .init.text:pcibios_map_irq() The function pcibios_scanbus() references the function __init pcibios_map_irq(). This is often because pcibios_scanbus lacks a __init annotation or the annotation of pcibios_map_irq is wrong. Run-Tested only on Alchemy.
