The SKF_AD_ALU_XOR_X ancillary is not like the other ancillary data
instructions since it XORs A with X while all the others replace A with
some loaded value.  All the BPF JITs fail to clear A if this is used as
the first instruction in a filter.

Is x86_64 part of this 'All' subset ? ;)

No, because it's an eBPF JIT.
