Hi Alistair,
kernel test robot noticed the following build errors:

Once the lazy preemption is supported, it would be desirable to change
the preemption models at runtime. So this change adds support for dynamic
preemption using DYNAMIC_KEY.
In irq-exit to kernel path, use preempt_model_preemptible for decision.
Other way would be using static key based decision.
Preemption models can change at runtime with dynamic preemption in
place. So need to use the right methods instead of relying on
CONFIG_PREEMPT to decide whether its full preemption or not.
While there, fix it to print preemption model correctly.

PowerPC uses asm-generic preempt definitions as of now.
Copy that into arch/asm so that arch specific changes can be done.
This would help the next patch for enabling dynamic preemption.
No functional changes intended.

Once the lazy preemption is supported, it makes sense to enable dynamic
preemption. One can change the preemption model without changing the
kernel.
Overheads of dynamic preemption seems reasonable for some of the
workloads. Tested with db2 database workload, unixbench, schbench
and hackbench. Ex

Nope. I was thinking about the same thing, but we actually don't look
up the fault handler early - we only do it at failure time.
So the pagefault_
