Xi Wang 1e4df6b720 arm64: bpf: fix signedness bug in loading 64-bit immediate ... Consider "(u64)insn1.imm << 32 | imm" in the arm64 JIT. Since imm is signed 32-bit, it is sign-extended to 64-bit, losing the high 32 bits. The fix is to convert imm to u32 first, which will be zero-extended to u64 implicitly.
