f61bb93927 ACPI: WMI: use .notify method instead of installing handler directly
This patch adds a .notify() method.  The presence of .notify() causes
Linux/ACPI to manage event handlers and notify handlers on our behalf,
so we don't have to install and remove them ourselves.

a74dd5fdab acer-wmi: Blacklist Acer Aspire One
The Aspire One's ACPI-WMI interface is a placeholder that does nothing,
and the invalid results that we get from it are now causing userspace
problems as acer-wmi always returns that the rfkill is enabled (i.e. the
radio is off, when it isn't). As it's hardware controlled, acer-wmi
isn't needed on the Aspire One either.

Thanks to Andy Whitcroft at Canonical for tracking down Ubuntu's userspace
issues to this.

0e501834f8 thinkpad-acpi: rework brightness support
Refactor and redesign the brightness control backend...

In order to fix bugzilla #11750...

Add a new brightness control mode: support direct NVRAM checkpointing
of the backlight level (i.e. store directly to NVRAM without the need
for UCMS calls), and use that together with the EC-based control.
Disallow UCMS+EC, thus avoiding races with the SMM firmware.

Switch the models that define HBRV (EC Brightness Value) in the DSDT
to the new mode.  These are: T40-T43, R50-R52, R50e, R51e, X31-X41.

Change the default for all other IBM ThinkPads to UCMS-only.  The
Lenovo models already default to UCMS-only.

a4d5effcc7 thinkpad-acpi: restrict access to some firmware LEDs
Some of the ThinkPad LEDs indicate critical conditions that can cause
data loss or cause hardware damage when ignored (e.g. force-ejecting
a powered up bay; ignoring a failing battery, or empty battery; force-
undocking with the dock buses still active, etc).

On almost all ThinkPads, LED access is write-only, and the firmware
usually does fire-and-forget signaling on them, so you effectively
lose whatever message the firmware was trying to convey to the user
when you override the LED state, without any chance to restore it.

Restrict access to all LEDs that can convey important alarms, or that
could mislead the user into incorrectly operating the hardware.  This
will make the Lenovo engineers less unhappy about the whole issue.

Allow users that really want it to still control all LEDs, it is the
unaware user that we have to worry about.

2586d5663d thinkpad-acpi: remove HKEY disable functionality
The HKEY disable functionality basically cripples the entire event
model of the ThinkPad firmware and of the thinkpad-acpi driver.
Remove this functionality from the driver.  HKEY must be enabled at
all times while thinkpad-acpi is loaded, and disabled otherwise.

For sysfs, according to the sysfs ABI and the thinkpad-acpi sysfs
rules of engagement, we will just remove the attributes.  This will be
done in two stages: disable their function now, after two kernel
releases, remove the attributes.

For procfs, we call WARN().  If nothing triggers it, I will simply
remove the enable/disable commands entirely in the future along with
the sysfs attributes.

I don't expect much, if any fallout from this.  There really isn't any
reason to mess with hotkey_enable or with the enable/disable commands
to /proc/acpi/ibm/hotkey, and this has been true for years...

Add a debug helper that discloses the TGID of the userspace task
attempting to access the driver.  This is highly useful when dealing
with bug reports, since often the user has no idea that some userspace
application is accessing thinkpad-acpi...

Also add a helper to log warnings about sysfs attributes that are
deprecated.

Use the new helpers to issue deprecation warnings for bluetooth_enable
and wwan_enabled, that have been deprecated for a while, now.

07de5bdb7b tc1100-wmi: Fix state reporting
The tc1100-wmi driver should print the current states of wireless LAN and
jogdial brightness control when "cat /sys/devices/platform/tc1100-wmi/wireless"
and "cat /sys/devices/platform/tc1100-wmi/jogdial" are executed, respectively.
What actually happens is that both of those commands print 0 regardless of the
hardware state. The cause is that wmi_query_block returns an ACPI_TYPE_INTEGER
rather than ACPI_TYPE_BUFFER as the driver assumes. Additionally, the driver
intends to return a jogdial state that is inverted with respect to the commands
required to set it (e.g. it intends to return 1 after the jogdial file was
written with 0).

This patch fixes both of those issues - the commands to query the
state now work, and should return the same state that was written.

99b7623380 proc 2/2: remove struct proc_dir_entry::owner
Setting ->owner as done currently (pde->owner = THIS_MODULE) is racy
as correctly noted at bug #12454. Someone can lookup entry with NULL
->owner, thus not pinning enything, and release it later resulting
in module refcount underflow.

We can keep ->owner and supply it at registration time like ->proc_fops
and ->data.

But this leaves ->owner as easy-manipulative field (just one C assignment)
and somebody will forget to unpin previous/pin current module when
switching ->owner. ->proc_fops is declared as "const" which should give
some thoughts.

->read_proc/->write_proc were just fixed to not require ->owner for
protection.

rmmod'ed directories will be empty and return "." and ".." -- no harm.
And directories with tricky enough readdir and lookup shouldn't be modular.
We definitely don't want such modular code.

Removing ->owner will also make PDE smaller.

So, let's nuke it.

Kudos to Jeff Layton for reminding about this, let's say, oversight.

1cae710321 sony-laptop: VGN-A317M hotkey support
This laptop has 5 SPIC managed buttons above the keyboard:
sound + and - as well as brightness, zoom and S1.
Possibly the entire VGN-A serie behaves the same.
