With /sys/kernel/debug/acpi/custom_method root can write
to arbitrary memory and increase his priveleges, even if
these are restricted.

-> Make this an own debug .config option and warn about the
security issue in the config description.

-> Still keep acpi/debugfs.c which now only creates an empty
   /sys/kernel/debug/acpi directory. There might be other
   users of it later.

Jean Delvare 7d03336538 Move ACPI power meter driver to hwmon
As discussed earlier, the ACPI power meter driver would better live
in drivers/hwmon, as its only purpose is to create hwmon-style
interfaces for ACPI 4.0 power meter devices. Users are more likely to
look for it there, and less likely to accidentally hide it by
unselecting its dependencies.

David Rientjes 6a108a14fa kconfig: rename CONFIG_EMBEDDED to CONFIG_EXPERT
The meaning of CONFIG_EMBEDDED has long since been obsoleted; the option
is used to configure any non-standard kernel with a much larger scope than
only small devices.

This patch renames the option to CONFIG_EXPERT in init/Kconfig and fixes
references to the option throughout the kernel.  A new CONFIG_EMBEDDED
option is added that automatically selects CONFIG_EXPERT when enabled and
can be used in the future to isolate options that should only be
considered for embedded systems (RISC architectures, SLOB, etc).

Calling the option "EXPERT" more accurately represents its intention: only
expert users who understand the impact of the configuration changes they
are making should enable it.

Zhang Rui 6d855fcdd2 ACPI: delete CONFIG_ACPI_PROCFS_POWER and power procfs I/F in 2.6.39
sysfs I/F for ACPI power devices, including AC and Battery,
has been working in upstream kenrel since 2.6.24, Sep 2007.
In 2.6.37, we made the sysfs I/F always built in and this option
disabled by default.
Now, we plan to remove this option and the ACPI power procfs
interface in 2.6.39.

First, update the feature-removal-schedule to announce this change.
Second, add runtime warnings in ACPI AC/Battery/SBS driver, so that
users will notice this change even if "make oldconfig" is used.

Zhang Rui 4464ed3b05 ACPI: update CONFIG_ACPI_PROCFS description
Update CONFIG_ACPI_PROCFS description because the processor,
video and thermal zone procfs I/F have been removed.

Some ACPI drivers, e.g. button, have their procfs I/F always built in,
because we don't have sysfs I/F replacement at the moment.
But once we finish developing the sysfs I/F for these driver,
we need CONFIG_ACPI_PROCFS to enabled/disable the corresponding procfs I/F.

So just updating the description rather than removing this option,
although there is no procfs I/F depends on it for now.

Zhao Yakui e92b297cc7 IPMI/ACPI: Add the IPMI opregion driver to enable ACPI to access BMC controller
ACPI 4.0 spec adds the ACPI IPMI opregion, which means that the ACPI AML
code can also communicate with the BMC controller. This is to install
the ACPI IPMI opregion and enable the ACPI to access the BMC controller
through the IPMI message.

     It will create IPMI user interface for every IPMI device detected
in ACPI namespace and install the corresponding IPMI opregion space handler.
Then it can enable ACPI to access the BMC controller through the IPMI
message.

The following describes how to process the IPMI request in IPMI space handler:
    1. format the IPMI message based on the request in AML code.
    IPMI system address. Now the address type is SYSTEM_INTERFACE_ADDR_TYPE
    IPMI net function & command
    IPMI message payload
    2. send the IPMI message by using the function of ipmi_request_settime
    3. wait for the completion of IPMI message. It can be done in different
routes: One is in handled in IPMI user recv callback function. Another is
handled in timeout function.
    4. format the IPMI response and return it to ACPI AML code.

At the same time it also addes the module dependency. The ACPI IPMI opregion
will depend on the IPMI subsystem.

Beside the fact that /proc/acpi is deprecated for quite some time,
this info is not needed for applications and thus can be moved

Huang Ying a643ce207f ACPI, APEI, APEI supporting infrastructure
APEI stands for ACPI Platform Error Interface, which allows to report
errors (for example from the chipset) to the operating system. This
improves NMI handling especially. In addition it supports error
serialization and error injection.

For more information about APEI, please refer to ACPI Specification
version 4.0, chapter 17.

This patch provides some common functions used by more than one APEI
tables, mainly framework of interpreter for EINJ and ERST.

A machine readable language is defined for EINJ and ERST for OS to
execute, and so to drive the firmware to fulfill the corresponding
functions. The machine language for EINJ and ERST is compatible, so a
common framework is defined for them.

This driver exposes ACPI 4.0 compliant power meters as hardware monitoring
devices.  This second revision of the driver also exports the ACPI string
info as sysfs attributes, a list of the devices that the meter measures,
and will send ACPI notifications over the ACPI netlink socket.  This
latest revision only enables the power capping controls if it can be
confirmed that the power cap can be enforced by the hardware and explains
how the notification interfaces work.

Shaohua Li 8e0af5141a ACPI: create Processor Aggregator Device driver
ACPI 4.0 created the logical "processor aggregator device" as
a mechinism for platforms to ask the OS to force otherwise busy
processors to enter (power saving) idle.

The intent is to lower power consumption to ride-out
transient electrical and thermal emergencies,
rather than powering off the server.

On platforms that can save more power/performance via P-states,
the platform will first exhaust P-states before forcing idle.
However, the relative benefit of P-states vs. idle states
is platform dependent, and thus this driver need not know
or care about it.

This driver does not use the kernel's CPU hot-plug mechanism
because after the transient emergency is over, the system must
be returned to its normal state, and hotplug would permanently
break both cpusets and binding.

So to force idle, the driver creates a power saving thread.
The scheduler will migrate the thread to the preferred CPU.
The thread has max priority and has SCHED_RR policy,
so it can occupy one CPU.  To save power, the thread will
invoke the deep C-state entry instructions.

To avoid starvation, the thread will sleep 5% of the time
time for every second (current RT scheduler has threshold
to avoid starvation, but if other CPUs are idle,
the CPU can borrow CPU timer from other,
which makes the mechanism not work here)

Vaidyanathan Srinivasan has proposed scheduler enhancements
to allow injecting idle time into the system.  This driver doesn't
depend on those enhancements, but could cut over to them
when they are available.

Peter Z. does not favor upstreaming this driver until
the those scheduler enhancements are in place.  However,
we favor upstreaming this driver now because it is useful
now, and can be enhanced over time.

Alex Chiang 268a03a42d PCI: drivers/pci/slot.c should depend on CONFIG_SYSFS
There is no way to interact with a physical PCI slot without
sysfs, so encode the dependency and prevent this build error:

	drivers/pci/slot.c: In function 'pci_hp_create_module_link':
	drivers/pci/slot.c:327: error: 'module_kset' undeclared

This patch _should_ make pci-sysfs.o depend on CONFIG_SYSFS too,
but we cannot (yet) because the PCI core merrily assumes the
existence of sysfs:

	drivers/built-in.o: In function `pci_bus_add_device':
	drivers/pci/bus.c:89: undefined reference to `pci_create_sysfs_dev_files'
	drivers/built-in.o: In function `pci_stop_dev':
	drivers/pci/remove.c:24: undefined reference to `pci_remove_sysfs_dev_files'

So do the minimal bit for now and figure out how to untangle it
later.

    OSPM must make Embedded Controller operation regions, accessed
    via the Embedded Controllers described in ECDT, available before
    executing any control method.

The ECDT table is optional, but if it is present, the above text
means that the EC it describes is a required part of the ACPI
subsystem, so CONFIG_ACPI_EC=n wouldn't make sense.

Bjorn Helgaas fefe5ab3d6 ACPI: remove CONFIG_ACPI_POWER
Remove CONFIG_ACPI_POWER.  It was always set the same as CONFIG_ACPI,
and it had no menu label, so there was no way to set it to anything
other than "y".

The interfaces under CONFIG_ACPI_POWER (acpi_device_sleep_wake(),
acpi_power_transition(), etc) are called unconditionally from the
ACPI core, so we already depend on it always being present.

Rafael J. Wysocki 5d1e072b6b ACPI suspend: Fix CONFIG_ACPI_SLEEP dependence and some compilation warnings
Initially CONFIG_PM_SLEEP was defined as
CONFIG_SUSPEND || CONFIG_HIBERNATION and some ACPI code, most
importantly the code in drivers/acpi/main.c, was written with this
assumption.  Currently, however, CONFIG_PM_SLEEP is also set when
CONFIG_XEN_SAVE_RESTORE is set.

This causes some compilation warnings to appear in
drivers/acpi/main.c if both CONFIG_SUSPEND and CONFIG_HIBERNATION
are unset and CONFIG_PM_SLEEP is set (this was impossible before).
To fix this problem, redefine CONFIG_ACPI_SLEEP do depend directly
on CONFIG_SUSPEND || CONFIG_HIBERNATION, as originally intended, and
use it instead of CONFIG_PM_SLEEP in drivers/acpi/main.c, wherever
appropriate.

Additionally, move the acpi_target_sleep_state definition from under
the #ifdef to prevent compilation from failing in some cases.

philipl@overt.org c41a40c58b toshiba_acpi: Add support for bluetooth toggling through rfkill (v8)
There's been a patch floating around for toshiba_acpi that exports an ad-hoc
/proc interface to toggle the bluetooth adapter in a large number of Toshiba
laptops. I'm not sure if it's still relevant for the latest models, but it is
still required for older models such as my Tecra M3.

This change pulls in the low level Toshiba-specific code from the old patch and
sets up an rfkill device and a polled input device to track the state of the
hardware kill-switch.
