Hi Cedric,
I was about to apply the series, but then I found the following problem.

opal_index is u32, so this won't work (or at least the result is
unpredictable).
Also, in patch 4/4 (v4), get_logical_cpu() takes unsigned int as parameter,
but get_hard_smp_processor_id() returns an int, causing gcc to complain
if the code is built with W=1.
Please fix and resubmit the entire series.
When you do that, please also ensure that continuation lines
are aligned (in patch 3/4).
Thanks,
Guenter
