在 google 查到的都是说arch/arm/kernel/vmlinux.lds的最后两行(如下)，给注释起来，但是没说为什么
ASSERT((__proc_info_end - __proc_info_begin), "missing CPU support")
ASSERT((__arch_info_end - __arch_info_begin), "no machine record defined"
后来自己到 arch/arm/kernel/vmlinux.lds 看注释才知道
These must never be empty
If you have to comment these two assert statements out, your
binutils is too old (for other reasons as well)
在编译通过。
