I followed upstream Archlinux on this. It's still not my domain. My guess is, that I made a mistake, IOW I think that your config is better than mine. However, when I run make oldconfig, there only was one item asking me what to do. The default was "N". I simply pushed enter, insted of "?" and/or googleing. I should consider to follow Arch upstrem, too. OTOH an unpatched kernel is not aimed for real-time purposes, so a new feature might have unwanted impact on DSP load. Actually I prefer using your tarballs to build my kernels, since you add all those patches. The kernels I build that aren't based upon you traballs, usually are vanilla kernels + the rt-patch, but no other patch, let alone the config. Regarding rt and audio drivers my own configs should be as good as yours, but anything else of my configs could be fishy. Thank you for maintaining linux-rt :) and thank you for the /sys/devices/system/cpu/vulnerabilities/ pointer :).
