arch/powerpc/net/bpf_jit_comp64.c:415:46: error: implicit declaration
of function 'PPC_RAW_LI'; did you mean 'PPC_RLWIMI'?
PPC_RAW_LI() was added by commit 3a1812379163 ("powerpc/ppc-opcode:
Consolidate powerpc instructions from bpf_jit.h")
Priori to that you have to use PPC_LI() instead, with the same arguments.
