The timer broadcast code might access HPET, which should not be accessed after the busmaster disable. In acpi_idle_enter_simple() this change also prevents, that we modify the busmaster state without going actually idle. This might leave the ACPI bm state in a stale state, when we leave the function early in the need_resched() check.
