Implement involuntary preemption check
...
Prevent loading the kernel module if the kernel can be involuntarily
preempted
CAS will work if the kernel has been compiled with either
CONFIG_PREEMPT_NONE, CONFIG_PREEMPT_VOLUNTARY, or CONFIG_PREEMPT_DYNAMIC.
If the dynamic configuration is enabled, the kernel must be booted with
preempt=none or preempt=voluntary.
