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. # # Fixes: 8747bf36f312 ("powerpc/powernv/idle: Replace CPU feature check with PVR check") #
