Ah, this one:
cfe43f478b79 ("preempt/dynamic: Introduce preemption model accessors")
Please accept my apologies for the disruption. This commit was needed to be able to properly handle CONFIG_PREEMPT_DYNAMIC=y kernels booting with preempt=none or preempt=voluntary. But I should have called this out in my pull request, and failed to do so. Again, please accept my apologies for the disruption.
Thanx, Paul
