Michal Mielewczyk aa660ca0a5 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.
