S4 suspend to disk will disable GPE's permanently
because acpi_gpe_sleep_prepare() does not have
a counterpart at resume time. Thus, those devices
became unavailable for wakeup from subsequent
S3 suspend-to-ram.Here acpi_gpe_sleep_prepare() is removed, and upon suspend
acpi_enable_wakeup_device() gets its functionality.
Upon resume, acpi_disable_wakeup_device() restores the state.https://bugzilla.novell.com/show_bug.cgi?id=292300

The previous events patch added a netlink event for every
user of the legacy /proc/acpi/event interface.However, some users of /proc/acpi/event are really input events,
and they already report their events via the input layer.Introduce a new interface, acpi_bus_generate_netlink_event(),
which is explicitly called by devices that want to repoprt
events via netlink. This allows the input-like events
to opt-out of generating netlink events. In summary:events that are sent via netlink:
ac/battery/sbs
thermal
processor
thinkpad_acpi dock/bayevents that are sent via input layer:
button
video hotkey
thinkpad_acpi hotkey

Introduce CONFIG_SUSPEND representing the ability to enter system sleep
states, such as the ACPI S3 state, and allow the user to choose SUSPEND
and HIBERNATION independently of each other.Make HOTPLUG_CPU be selected automatically if SUSPEND or HIBERNATION has
been chosen and the kernel is intended for SMP systems.Also, introduce CONFIG_PM_SLEEP which is automatically selected if
CONFIG_SUSPEND or CONFIG_HIBERNATION is set and use it to select the
code needed for both suspend and hibernation.The top-level power management headers and the ACPI code related to
suspend and hibernation are modified to use the new definitions (the
changes in drivers/acpi/sleep/main.c are, mostly, moving code to reduce
the number of ifdefs).There are many other files in which CONFIG_PM can be replaced with
CONFIG_PM_SLEEP or even with CONFIG_SUSPEND, but they can be updated in
the future.Signed-off-by: Rafael J. Wysocki

Teach PNPACPI how to hook up its devices to their ACPI nodes, so that
pnpdev->dev.archdata points to the parallel acpi device node. Previously
this only worked for PCI, leaving a notable hole.Export "acpi_bus_type" so this can work.
Remove some extraneous whitespace.

Some of the ACPI devices use the internal fake hids
which are exposed to userspace as devces' bus_id after sysfs conversion.
To make it more friendly, we convert them to more understandable strings.For those devices w/o PNPids, we use "device:instance_no" as the bus_id
instead of "PNPIDNON:instance_no".Signed-off-by: Zhang Rui

We do this mainly because:
1. hid is used to match ACPI devices and drivers.
.match method which is incompatible to driver model
can be deleted from acpi_driver.ops then.
2. As the .uevent method mark ACPI drivers by PNPID,
fake hid is set to non-PNPID devices so that udev script
can load the right ACPI driver by looking for
"HWID = " or "COMPTID = ".Signed-off-by: Zhang Rui

Add removal_type in structure acpi_device for hot removal.

Add acpi_bus_ops in acpi_device to support acpi hot plug.
NOTE: Two methods .add and .start in acpi_driver.ops are
called separately to probe ACPI devices, while only
.probe method is called in driver model.
As executing .add and .start separately is critical
for ACPI device hot plug, we use acpi_bus_ops to
distinguish different code path.Signed-off-by: Zhang Rui

2. Add ACPI device in device tree.File "eject" for every device that has _EJ0 method is moved from
/sys/firmware to /sys/devices.

i.e. echo 1 to "eject" will cause hot removal of this device.

acpi_handle.It also removes the firmware_data field from struct device as this

Implemented header file support for the following
additional ACPI tables: ASF!, BOOT, CPEP, DBGP, MCFG, SPCR,
SPMI, TCPA, and WDRT. With this support, all current and
known ACPI tables are now defined in the ACPICA headers and
are available for use by device drivers and other software.Implemented support to allow tables that contain ACPI
names with invalid characters to be loaded. Previously,
this would cause the table load to fail, but since
there are several known cases of such tables on
existing machines, this change was made to enable
ACPI support for them. Also, this matches the
behavior of the Microsoft ACPI implementation.
https://bugzilla.novell.com/show_bug.cgi?id=147621Fixed a couple regressions introduced during the memory
optimization in the 20060317 release. The namespace
node definition required additional reorganization and
an internal datatype that had been changed to 8-bit was
restored to 32-bit. (Valery Podrezov)Fixed a problem where a null pointer passed to
acpi_ut_delete_generic_state() could be passed through
to acpi_os_release_object which is unexpected. Such
null pointers are now trapped and ignored, matching
the behavior of the previous implementation before the
deployment of acpi_os_release_object(). (Valery Podrezov,
Fiodor Suietov)Fixed a memory mapping leak during the deletion of
a SystemMemory operation region where a cached memory
mapping was not deleted. This became a noticeable problem
for operation regions that are defined within frequently
used control methods. (Dana Meyers)Reorganized the ACPI table header files into two main
files: one for the ACPI tables consumed by the ACPICA core,
and another for the miscellaneous ACPI tables that are
consumed by the drivers and other software. The various
FADT definitions were merged into one common section and
three different tables (ACPI 1.0, 1.0+, and 2.0)Signed-off-by: Bob Moore

Nobody looks at the return value, and this brings it into line with
pci_unregister_driver(), etc. Also removed validation of the driver
pointer passed in to register and unregister. More consistent, and we'll
find bugs faster if we fault rather than returning an error that's ignored.Also makes internal functions acpi_device_unregister() and
acpi_driver_detach() void, since nobody uses their returns either.Signed-off-by: Bjorn Helgaas
