Dear Johan, In arch/mips/net/bpf_jit_comp.h and introduced with commit commit 72570224bb8f ("mips, bpf: Add JIT workarounds for CPU errata"), there is an ifdef that refers to a non-existing symbol WAR_R10000. Did you intend to refer to WAR_R10000_LLSC instead? This issue was identified with the script ./scripts/checkkconfigsymbols.py. Best regards, Lukas
