If I'm understanding things correctly, you call this function in patch
3. Quoting from that patch:
+static void nest_init(void *dummy)
+{
+ opal_nest_ima_control(P8_NEST_ENGINE_START);
+}
Does this patch need to be moved earlier in the series?
I applied all the patches together and tested it since the Makefile inclusion is
the final patch in the series. I guess it is better rearrange the series.

Have you tested that the series compiles at every point?
(I've found that this can be done quite easily with
git rebase --interactive using x to run the compile)
Nice. will try this out.

Thanks for the review
