A value of 7 translates into a hint to balance performance with energy savings. The default reset value of the MSR is 0. If BIOS doesn't intialize the MSR, the hardware will run in performance state. This patch initialize the MSR with value of 7 for balance between performance and energy savings " enhancement closed normal R1 System/Kernel R1/alpha3 fixed gsoc2012 All
