Currently, ARB_DISABLE is a NOP on all of the recent Intel platforms. For such platforms, reduce contention on c3_lock by skipping the fake ARB_DISABLE. The cpu model id on one laptop is 14. If we disable ARB_DISABLE on this box, the box can't be booted correctly. But if we still enable ARB_DISABLE on this box, the box can be booted correctly. So we still use the ARB_DISABLE for the cpu which mode id is less than 0x0f. http://bugzilla.kernel.org/show_bug.cgi?id=14700Signed-off-by: NZhao Yakui <yakui.zhao@intel.com> Acked-by: NPallipadi, Venkatesh <venkatesh.pallipadi@intel.com> cc: stable@kernel.org Signed-off-by: NLen Brown <len.brown@intel.com>
