Based on comments from Nicholas Piggin, introducing a cleanup patch in which, instead of checking for CPU_FTR_ARCH_300 check for PVR_POWER9 to allow for a finer granularity of checks where one processor generation can have multiple ways to handling idle 2. Removed saving-restoring DAWR, DAWRX patch for P10 systems. Based on discussions it has become evident that checks based on PVR is the way to go; however, P10 PVR is yet to up-stream hence shelving this patch for later. Pratik Rajesh Sampat (3): powerpc/powernv/idle: Replace CPU features checks with PVR checks 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 | 38 +++++++++++++-------------- 1 file changed, 19 insertions(+), 19 deletions(-)
