Really the SPARC code (and any architectures added in the future with a

So I could turn the question around and ask: How many empty definitions
of this thing do you want in the tree?
I will defer to Steven. If he wants to push the empty stubs into all
the architectures, I will update the MIPS patch and he can remove/revert
the 'jump label: Make arch_jump_label_text_poke_early() optional' patch.
Let me know which option you would prefer.
On IRC, Thomas Gleixner mentioned a better solution (something I've done
with ftrace). Just add a "weak" stub function. No need to get Kconfig
involved.
