Don't use gcc plugins for building arch/arm/vdso/vgettimeofday.c to avoid unneeded instrumentation. As previously discussed[1]: arm_ssp_per_task_plugin.c 32-bit ARM only (but likely needs disabling for 32-bit ARM vDSO?) cyc_complexity_plugin.c compile-time reporting only latent_entropy_plugin.c this shouldn't get triggered for the vDSO (no __latent_entropy nor __init attributes in vDSO), but perhaps explicitly disabling it would be a sensible thing to do, just for robustness? randomize_layout_plugin.c this shouldn't get triggered (again, lacking attributes), but should likely be disabled too. sancov_plugin.c This should be tracking the KCOV directly (see scripts/Makefile.kcov), which is already disabled here. structleak_plugin.c This should be fine in the vDSO, but there's no security boundary here, so it wouldn't be important to KEEP it enabled.
