    With this .config: http://busybox.net/~vda/kernel_config,
    after uninlining these functions have sizes and callsite counts
    as follows:
    
    cfi_udelay(): 74 bytes, 26 callsites
    cfi_send_gen_cmd(): 153 bytes, 95 callsites
    cfi_build_cmd(): 274 bytes, 123 callsites
    cfi_build_cmd_addr(): 49 bytes, 15 callsites
    cfi_merge_status(): 230 bytes, 3 callsites
    
    Reduction in code size is about 50,000:
    
        text     data      bss       dec     hex filename
    85842882 22294584 20627456 128764922 7accbfa vmlinux.before
