Building with CONFIG_DEBUG_SECTION_MISMATCH gives the following warning: WARNING: vmlinux.o(.text+0x41fa8): Section mismatch in reference from the function .msi_bitmap_alloc() to the function .init.text:.memblock_virt_alloc_try_nid() The function .msi_bitmap_alloc() references the function __init .memblock_virt_alloc_try_nid(). This is often because .msi_bitmap_alloc lacks a __init annotation or the annotation of .memblock_virt_alloc_try_nid is wrong.
memory allocation in msi_bitmap_alloc use either slab allocator or memblock boot-time allocator so that's why we need the __init_refok for the latter case.
