Thanks to the nested inlining, all drivers correctly calling dma_mapping_error() after a mapping a page or single buffer generate two calls to get_arch_dma_ops() per callsite, which all adds up to a fair old chunk of useless code, e.g. ~3KB for an arm64 defconfig plus extras: text data bss dec hex filename 13051391 1503898 327768 14883057 e318f1 vmlinux.o.old 13050751 1503898 327768 14882417 e31671 vmlinux.o.new Give the compiler a hand by making it clear we want the same ops.
