Merge branch 'idle-release' of git://git.kernel.org/pub/scm/linux/kernel/git/lenb/linux-idle-2.6
* 'idle-release' of git://git.kernel.org/pub/scm/linux/kernel/git/lenb/linux-idle-2.6: intel_idle: native hardware cpuidle driver for latest Intel processors ACPI: acpi_idle: touch TS_POLLING only in the non-MWAIT case acpi_pad: uses MONITOR/MWAIT, so it doesn't need to clear TS_POLLING sched: clarify commment for TS_POLLING ACPI: allow a native cpuidle driver to displace ACPI cpuidle: make cpuidle_curr_driver static cpuidle: add cpuidle_unregister_driver() error check cpuidle: fail to register if !CONFIG_CPU_IDLE
