I've tried (from your tree, but I suppose that doesn't matter):
20d1c86 sched/clock, x86: Rewrite cyc2ns() to avoid the need to disable IRQs
57c67da sched/clock, x86: Move some cyc2ns() code around
5dd12c21 sched/clock, x86: Use mul_u64_u32_shr() for native_sched_clock()
62b94a0 sched/preempt: Take away preempt_enable_no_resched() from modules

and all of them fail to compile. Looking at the bisect log I attached when
submitting the bug report, I see that all of them are the same I had to skip
because they would not compile.

They all fail with:
