We are keeping tuning cpuidle. This patchset focuses on reducing unnecessary intrs & overheads. [PATCH 1/3] Fix VCPU periodic timer. Bypass useless idle vcpu timer to reduce intr num, and add a TIME_SLOP (50us) in vcpu periodic timer to remove multiple callings for firing. [PATCH 2/3] Fix acpi_set_register. Remove a redundant call to acpi_hw_register_read() in acpi_set_register() to reduce overheads. [PATCH 3/3] Disable ARB_DIS conditinally. Conditinally disable ARB_DIS after C3 exit to reduce overheads.
