# commit 16d83a540ca4e7f1ebb2b3756869b77451d31414

#     Revert "powerpc/powernv/idle: Replace CPU feature check with PVR check"
#     
#     cpuidle stop state implementation has minor optimizations for P10
#     where hardware preserves more SPR registers compared to P9. The
#     current P9 driver works for P10, although does few extra
#     save-restores. P9 driver can provide the required power management
#     features like SMT thread folding and core level power savings on a P10
#     platform.
#     
#     Until the P10 stop driver is available, revert the commit which allows
#     for only P9 systems to utilize cpuidle and blocks all idle stop states
#     for P10. CPU idle states are enabled and tested on the P10 platform
#     with this fix.
#     
#     This reverts commit 8747bf36f312356f8a295a0c39ff092d65ce75ae.
