You copied the wrong section:
 
config PREEMPT_DYNAMIC
bool "Preemption behaviour defined on boot"
depends on HAVE_PREEMPT_DYNAMIC
select JUMP_LABEL if HAVE_PREEMPT_DYNAMIC_KEY
select PREEMPT_BUILD
default y if HAVE_PREEMPT_DYNAMIC_CALL
help
  This option allows to define the preemption model on the kernel
  command line parameter and thus override the default preemption
  model defined during compile time.
 
***---->  The feature is primarily interesting for Linux distributions which
  provide a pre-built kernel binary to reduce the number of kernel
  flavors they offer while still offering different usecases.
 
  The runtime overhead is negligible with HAVE_STATIC_CALL_INLINE enabled
  but if runtime patching is not available for the specific architecture
  then the potential overhead should be considered.
 
  Interesting if you want the same pre-built kernel should be used for
  both Server and Desktop workloads.

Eh, I'll give you that one, because I had it checked.  Standby on that.

Meanwhile, you *still* haven't posted your uname -a, and you *still*
haven't built the latest Pan, and you *still* haven't posted
your "perfect" C code that uses gmp to compute subfactorials.

(BTW, have you figured out yet why you don't want PREEMPT_LAZY?)
