I couldn't find a kselftests .config in the tree (assumedly I'm just ont
looking hard enough), but does that happen to enable CONFIG_STACK_TRACER=y?
If so, since you're using clang, I wonder if this is an issue with
68a63a412d18 ("arm64: Fix build with CC=clang, CONFIG_FTRACE=y and
CONFIG_STACK_TRACER=y")?
Please let us know how the bisection goes...
