Now that preempt=lazy patches[1] are in powerpc-next tree, sending out the patch to support dynamic preemption based on DYNAMIC_KEY.
base: powerpc-next Once the arch supports static inline calls, it would be needed to evaluate to see if that gives better performance. v2->v3: - fixed a build error reported by linux test robot by including jump label header. v1->v2: - Instead of copying asm-generic preempt.h content include it in arch/asm preempt.h.
