Hello Nick & Cedric,
Based on your comments on considering the pseries for 9.1, and having to
wait for skiboot parts for powernv, I have split the patch series into
pseries and powernv.
There might be little delay in posting the powernv part, where I am
still looking into having power11's instance_init.
Also, I have applied Harsh's patch that should simplify the rest of the
patches.
Thanks,
Aditya Gupta
