Bhat +++ This bug was initially created as a clone of Bug #163527 +++ ---Problem Description--- Error in CPU frequency reporting when nominal and min pstates are same The patch for this issue is accepted to linux-next as 3fa4680b860bf48b437d6a2c039789c4abe202ae cpufreq: powernv: Dont assume distinct pstate values for nominal and pmin Some OpenPOWER boxes can have same pstate values for nominal and pmin pstates. In these boxes the current code will not initialize 'powernv_pstate_info.min' variable and result in erroneous CPU frequency reporting. This patch fixes this problem.
