14e04fb34f ACPI: Schedule /proc/acpi/event for removal
Schedule /proc/acpi/event for removal in 6 months.

Re-name acpi_bus_generate_event() to acpi_bus_generate_proc_event()
to make sure there is no confusion that it is for /proc/acpi/event only.

Add CONFIG_ACPI_PROC_EVENT to allow removal of /proc/acpi/event.
There is no functional change if CONFIG_ACPI_PROC_EVENT=y

962ce8ca06 ACPI: don't duplicate input events on netlink
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/bay

events that are sent via input layer:
	button
	video hotkey
	thinkpad_acpi hotkey
	asus_acpi/asus-laptop hotkey
	sonypi/sonylaptop

5b31d89587 Revert "ACPI: Battery: Synchronize battery operations."
This reverts commit 3bd92ba19a.

It is no longer necessary, and it opens up a race.

b6ce4083ed ACPI: Cache battery status instead of re-evaluating AML
/proc exports _BST in a single file, and _BST is re-evaulated
whenever that file is read.

Sometimes user-space reads this file frequently, and on some
systems _BST takes a long time to evaluate due to a slow EC.

Further, when we move to sysfs, the values returned from _BST
will be in multiple files, and evaluating _BST for each
file read would make matters worse.

Here code is added to support caching the results of _BST.
A new module parameter "update_time" tells how many seconds the
cached _BST should be used before it is re-evaluated.
Currently, update_time defaults to 0, and so the
existing behaviour of re-evaluating on each read retained.

5d9464a469 ACPI: add ACPI bus_type for driver model
Add ACPI bus_type for Linux driver model.

1.	.shutdown method is added into acpi_driver.ops
	needed by bus_type operations.
2.	remove useless parameter 'int state' in .resume method.
3.	change parameter 'int state'
	to 'pm_message_t state' in .suspend method.

Note:	The new .uevent method mark ACPI drivers by PNPID instead of by name.
	Udev script needs to look for "HWID=" or "COMPTID=" to load
	ACPI drivers as a result.

1da177e4c3 Linux-2.6.12-rc2
Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
