What were the 4.19.80 build errors?
For the older kernels, it would have to be confirmed those kernels are
definietly affected. The test machines I tried fails to even boot on those
kernels so I need to find a NUMA machine that is old enough to boot those
kernels and confirmed affected by the bug before determining what the
backport needs to look like.
