Avoid TLB flush IPIs for the cores in deeper c-states by voluntary leave_mm() before entering into that state. CPUs tend to flush TLB in those c-states anyways. acpi_idle does this with C3-type states, but it was not caried over when intel_idle was introduced. intel_idle can apply it to C-states in addition to those that ACPI might export as C3...
