Before a cpuidle driver with one (C1, halt) state got registered Now the default_idle function will be used which finally uses the same idle call to enter sleep state (safe_halt()), but without registering a whole cpuidle driver. That means idle= param will always avoid cpuidle drivers to register with one exception (same behavior as before): idle=nomwait may still register acpi_idle cpuidle driver, but C1 will not use mwait, but hlt. This can be a workaround for IO based deeper sleep states where C1 mwait causes problems.

Therefore apply this only to uses of __get_cpu_var where the addres of the variable is not used.

This leads to a problem when the device's _PRW method points to a GPE, because in that case the GPE may be enabled by ACPICA during the subsequent acpi_update_gpes() call which, in turn, may cause a GPE storm to appear. To avoid this issue, make acpi_bus_check_add() evaluate _PRW for inactive or not present devices and register the wakeup GPE information returned by them, so that acpi_update_gpes() does not enable their GPEs unnecessarily.

So it need to use raw spinlock instead of normal spinlock. This patch fixes it. Signed-off-by: Huang Ying <ying.huang@intel.com> Signed-off-by: Len Brown <len.brown@intel.com>

Fix the problem by checking if the current device state is different from the new state before reference counting and turning on power resources in acpi_power_transition().

This touches lots of files mainly because of how the io_apic nmi_watchdog was implemented. Now that the io_apic nmi_watchdog is forever gone, remove all its fingers. Most of this code was not being exercised by virtue of nmi_watchdog != NMI_IO_APIC, so there shouldn't be anything to risky here.

As a result, the sysfs I/F of these dynamic tables are located at /sys/firmware/acpi/tables instead of /sys/firmware/acpi/tables/dynamic, which is not true. Invoke acpi_sysfs_init() before acpi_early_processor_set_pdc(), so that the table handler is installed before any dynamic tables loaded. https://bugzilla.kernel.org/show_bug.cgi?id=21142 CC: Dennis Jansen <dennis.jansen@web.de> CC: Alex Chiang <achiang@hp.com> Signed-off-by: Zhang Rui <rui.zhang@intel.com> Signed-off-by: Len Brown <len.brown@intel.com>
