[PATCH v3 0/1] powerpc: Enable dynamic preemption

[Shrikanth Hegde <sshegde@linux.ibm.com>]

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. (Christophe Leroy)
- Merge the patches into one patch (Christophe Leroy)
