Changed the naming of pnv_first_spr_loss_level from pnv_first_fullstate_loss_level to deep_spr_loss_state 2. Make the P9 PVR check only on the top level function pnv_probe_idle_states and let the rest of the checks be DT based because it is faster to do so Pratik Rajesh Sampat (3): powerpc/powernv/idle: Replace CPU features check with PVR check powerpc/powernv/idle: Rename pnv_first_spr_loss_level variable powerpc/powernv/idle: Exclude mfspr on HID1,4,5 on P9 and above arch/powerpc/platforms/powernv/idle.c | 26 +++++++++++++------------- 1 file changed, 13 insertions(+), 13 deletions(-)
