If anyone has any objections, please let me know. ------------------ From: Srinivas Pandruvada commit 9462e74c5c983cce34019bfb27f734552bebe59f upstream. After resume/online turbo limit ratio (TRL) is restored partially if the admin explicitly changed TRL from user space. A hash table is used to store SST mail box and MSR settings when modified to restore those settings after resume or online. This uses a struct isst_cmd field "data" to store these settings. This is a 64 bit field. But isst_store_new_cmd() is only assigning as u32. This results in truncation of 32 bits. Change the argument to u64 from u32.
