There exists failure when executing the testcase "./test_verifier 190" if CONFIG_HAVE_EFFICIENT_UNALIGNED_ACCESS is not set on LoongArch. #190/p calls: two calls that return map_value with incorrect bool check FAIL ... misaligned access off (0x0; 0xffffffffffffffff)+0 size 8 ... Summary: 0 PASSED, 0 SKIPPED, 1 FAILED It means that the program has unaligned accesses, but the kernel sets CONFIG_ARCH_STRICT_ALIGN by default to enable -mstrict-align to prevent unaligned accesses, so add a flag F_NEEDS_EFFICIENT_UNALIGNED_ACCESS into the testcase to avoid the failure. This is somehow similar with the commit ce1f289f541e ("selftests/bpf: Add F_NEEDS_EFFICIENT_UNALIGNED_ACCESS to some tests").
