swiotlb: add missing __init annotations
Impact: cleanup, reduce kernel size a bit The current kernel build warns: WARNING: vmlinux.o(.text+0x11458): Section mismatch in reference from the function swiotlb_alloc_boot() to the function .init.text:__alloc_bootmem_low() The function swiotlb_alloc_boot() references the function __init __alloc_bootmem_low(). This is often because swiotlb_alloc_boot lacks a __init annotation or the annotation of __alloc_bootmem_low is wrong. WARNING: vmlinux.o(.text+0x1011f2): Section mismatch in reference from the function swiotlb_late_init_with_default_size() to the function .init.text:__alloc_bootmem_low() The function swiotlb_late_init_with_default_size() references the function __init __alloc_bootmem_low(). This is often because swiotlb_late_init_with_default_size lacks a __init annotation or the annotation of __alloc_bootmem_low is wrong. and indeed the functions calling __alloc_bootmem_low() can be marked __init as well.
