Help text

An architecture should select this if it can handle the preemption model being selected at boot time using static calls.

Where an architecture selects HAVE_STATIC_CALL_INLINE, any call to a preemption function will be patched directly.

Where an architecture does not select HAVE_STATIC_CALL_INLINE, any call to a preemption function will go through a trampoline, and the trampoline will be patched.

It is strongly advised to support inline static call to avoid any overhead.
