All these changes look sane to me. I had to do few minor adjustments to
"UBUNTU: [Config] Enable CONFIG_UBSAN_BOUNDS", in particular:

 - CONFIG_UBSAN_SANITIZE_ALL can't be enabled on armhf, simply because
   the arch doesn't support it (so I just disabled it for armhf)

 - updated annotations to match 'n' vs '-' (option disabled vs option
   not available)

With these minor changes: applied to impish:linux 5.13.
