This is the last samples/bpf patch to fix the obvious build issues when make M=samples/bpf on the MIPS Loongson64 platform. There is another MIPS patch to fix the following build error when make M=samples/bpf, but it seems a common and known issue when build MIPS kernel used with clang [1]: ./arch/mips/include/asm/checksum.h:161:9: error: unsupported inline asm: input with type 'unsigned long' matching output with type '__wsum' (aka 'unsigned int') : "0" ((__force unsigned long)daddr), ^~~~~~~~~~~~~~~~~~~~~~~~~~~~ 1 error generated. Because these two patches are independent, this one is bpf-next related, the other one is mips-next related, so I submit them sepearately.

There exists many build errors when make M=samples/bpf on the Loongson platform, this issue is MIPS related, x86 compiles just fine.
