Hi,
This patch is a workaround of AMD erratum 411 for family 10h CPUs. This does 
not cause functional issues but may reduce the power saving effectiveness of 
message-triggered C1e mode. This would normally occur only if OS which has 
used the local APIC timer masks the interrupt without clearing Timer Initial 
Count Register.

Thanks,
Wei
