mwait_idle() is a C1-only idle loop intended to be more efficient
than HLT, starting on Pentium-4 HT-enabled processors.
But mwait_idle() has been replaced by the more general
mwait_idle_with_hints(), which handles both C1 and deeper C-states.
ACPI processor_idle and intel_idle use only mwait_idle_with_hints(),
and no longer use mwait_idle().
Here we simplify the x86 native idle code by removing mwait_idle(),
and the "idle=mwait" bootparam used to invoke it.
Since Linux 3.0 there has been a boot-time warning when "idle=mwait"
was invoked saying it would be removed in 2012. This removal
was also noted in the (now removed:-) feature-removal-schedule.txt.
After this change, kernels configured with
(CONFIG_ACPI=n && CONFIG_INTEL_IDLE=n) when run on hardware
that supports MWAIT will simply use HLT. If MWAIT is desired
on those systems, cpuidle and the cpuidle drivers above
can be enabled.

Enable ACPI SCI during suspend so that SCI can be used
as wake events for PM_SUSPEND_FREEZE.
For S3/S4 transition,
We disable all GPEs in suspend_ops->prepare_late() to
fix a problem that GPEs may trigger SCI before
arch_suspend_disable_irqs() is run.
So it is safe to leave the SCI enabled until
arch_suspend_irq_disable() is run.

If _PS0 is defined for an ACPI device node, but _PSC isn't and
the device node doesn't use power resources for power management,
acpi_bus_update_power() will fail to update the power state of it,
because acpi_device_get_power() returns ACPI_STATE_UNKNOWN in that
case.
To handle that situation make acpi_bus_update_power() follow
acpi_bus_init_power() and try to force the given device node into
power state D0.

In general, for ACPI device power management to work, the initial
power states of devices must be known (otherwise, we wouldn't be able
to keep track of power resources, for example). Hence, if it is
impossible to determine the initial ACPI power states of some
devices, they can't be regarded as power-manageable using ACPI.
For this reason, modify acpi_bus_get_power_flags() to clear the
power_manageable flag if acpi_bus_init_power() fails and add some
extra fallback code to acpi_bus_init_power() to cover broken
BIOSes that provide _PS0/_PS3 without _PSC for some devices.
Verified to work on my HP nx6325 that has this problem.

Originally 'efi_enabled' indicated whether a kernel was booted from
EFI firmware. Over time its semantics have changed, and it now
indicates whether or not we are booted on an EFI machine with
bit-native firmware, e.g. 64-bit kernel with 64-bit firmware.
The immediate motivation for this patch is the bug report at,
https://bugs.launchpad.net/ubuntu-cdimage/+bug/1040557
which details how running a platform driver on an EFI machine that is
designed to run under BIOS can cause the machine to become
bricked. Also, the following report,
https://bugzilla.kernel.org/show_bug.cgi?id=47121
details how running said driver can also cause Machine Check
Exceptions. Drivers need a new means of detecting whether they're
running on an EFI machine, as sadly the expression,
if (!efi_enabled)
hasn't been a sufficient condition for quite some time.
Users actually want to query 'efi_enabled' for different reasons -
what they really want access to is the list of available EFI
facilities.
For instance, the x86 reboot code needs to know whether it can invoke
the ResetSystem() function provided by the EFI runtime services, while
the ACPI OSL code wants to know whether the EFI config tables were
mapped successfully. There are also checks in some of the platform
driver code to simply see if they're running on an EFI machine (which
would make it a bad idea to do BIOS-y things).
This patch is a prereq for the samsung-laptop fix patch.

Currently, the ACPI namespace scanning code creates platform device
objects for ACPI device nodes whose IDs match the contents of the
acpi_platform_device_ids[] table. However, this adds a superfluous
special case into acpi_bus_device_attach() and makes it more
difficult to follow than it has to be. It also will make it more
difficult to implement removal code for those platform device objects
in the future.
For the above reasons, introduce a struct acpi_scan_handler object
for creating platform devices and move the code related to that from
acpi_bus_device_attach() to the .attach() callback of that object.
Also move the acpi_platform_device_ids[] table to acpi_platform.c.

Make the ACPI PCI IRQ link driver use struct acpi_scan_handler
for representing the object used to set up ACPI interrupt links and
to remove data structures used for this purpose before unregistering
the corresponding ACPI device nodes.
This simplifies the code slightly and reduces the kernel's memory
footprint by avoiding the registration of a struct device_driver
object with the driver core and creation of its sysfs directory
which is unnecessary.

Introduce struct acpi_scan_handler for representing objects that
will do configuration tasks depending on ACPI device nodes'
hardware IDs (HIDs).
Currently, those tasks are done either directly by the ACPI namespace
scanning code or by ACPI device drivers designed specifically for
this purpose. None of the above is desirable, however, because
doing that directly in the namespace scanning code makes that code
overly complicated and difficult to follow and doing that in
"special" device drivers leads to a great deal of confusion about
their role and to confusing interactions with the driver core (for
example, sysfs directories are created for those drivers, but they
are completely unnecessary and only increase the kernel's memory
footprint in vain).

acpi_add_single_object() to be dropped and the manipulation of the

Observe that acpi_get_child() doesn't need to use the helper
struct acpi_find_child structure and change it to work without it.
Also, using acpi_get_object_info() to get the output of _ADR for the
given device is overkill, because that function does much more than
just evaluating _ADR (let alone the additional memory allocation
done by it).
Moreover, acpi_get_child() doesn't need to loop any more once it has
found a matching handle, so make it stop in that case. To prevent
the results from changing, make it use do_acpi_find_child() as
a post-order callback.

This patch moves the host bridge hot-add support to pci_root.c and adds
hot-remove support in pci_root.c.
How to test it: if sci_emu patch is applied, find out root bus number to
ACPI root name mapping from dmesg or /sys. To remove root bus:
echo "\_SB.PCIB 3" > /sys/kernel/debug/acpi/sci_notify

During system resume we check if there are power resources that have
been turned off by the BIOS, but our reference counters for them
are nonzero (they need to be turned on then). It turns out, however,
that we also need to check the opposite, i.e. if there are power
resources that have been turned on by the BIOS, but our reference
counters for them are zero (which means that no devices are going
to need them any time soon) and we should turn them off.
Make the power resources resume code do the additional check and
turn off the unused power resources as appropriate.

Since ACPI power resources are going to be used more extensively on
new hardware platforms, it is necessary to allow user space (powertop
in particular) to look at the lists of power resources corresponding
to different power states of devices for diagnostics and control
purposes.
For this reason, for each power state of an ACPI device node using
power resources create a special attribute group under the device
node's directory in sysfs containing links to sysfs directories
representing the power resources in that list. The names of the
new attribute groups are "power_resources_<state>", where <state>
is the state name i.e. "D0", "D1", "D2", or "D3hot".

Implemented for both the compiler and the disassembler. Often,
the NOOP opcode is used as padding for packages that are changed
dynamically by the BIOS. When disassembled, these NOOPs will
cause syntax errors. This option causes the disassembler to ignore

Although the ACPI spec defines the \_Sx objects to return
a package containing one integer, most BIOS code returns two
integers and the previous code reflects that. However, we also
need to support BIOS code that actually implements to the ACPI
spec, and this change implements this.
