MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8

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.
