Len,
This patchset has most of my current thinkpad-acpi queue. The target is
2.6.25, I am submitting they early for testing in acpi-test.
As usual, the patch set is available at:
git://repo.or.cz/linux-2.6/linux-acpi-2.6/ibm-acpi-2.6.git for-upstream/acpi-test
The branch root is latest Linus' tree.
Shortlog of the above branch:
(these have been sent already, for 2.6.24-rc2)
ACPI: thinkpad-acpi: revert keymap changes
ACPI: thinkpad-acpi: support 16 levels of brightness (v3)
ACPI: thinkpad-acpi: add brightness_force parameter
ACPI: thinkpad-acpi: prefer standard ACPI backlight level control
ACPI: thinkpad-acpi: bump up version to 0.17
ACPI: thinkpad-acpi: allow for syscall restart in sysfs handlers
ACPI: thinkpad-acpi: fix brightness_set error paths
(these are new ones, for 2.6.25)
ACPI: thinkpad-acpi: refactor hotkey_get and hotkey_set
ACPI: thinkpad-acpi: prepare for NVRAM polling support
ACPI: thinkpad-acpi: add CMOS NVRAM polling for hot keys (v6)
ACPI: thinkpad-acpi: let threads be frozen
ACPI: thinkpad-acpi: bump up version to 0.18
ACPI: thinkpad-acpi: spring cleanup part 1
ACPI: thinkpad-acpi: spring cleanup part 2
ACPI: thinkpad-acpi: spring cleanup part 3
ACPI: thinkpad-acpi: spring cleanup part 4
ACPI: thinkpad-acpi: module glue cleanups
ACPI: thinkpad-acpi: rename IBM in defines
ACPI: thinkpad-acpi: some checkpatch.pl fluff
ACPI: thinkpad-acpi: add suspend handler
ACPI: thinkpad-acpi: cleanup hotkey_notify and HKEY log messages
ACPI: thinkpad-acpi: wakeup on hotunplug reporting
Please merge for acpi-test.
Thanks.

This patch:
1. Splits hotkey_get/set into hotkey_status_get/set and hotkey_mask_get/set;
2. Caches the status of hot key mask for later driver use;
3. Makes sure the cache of hot key mask is refreshed when needed;
4. logs a printk notice when the firmware doesn't set the hot key
mask to exactly what we asked it to;
5. Do the proper locking on the data structures.
Only (4) is user-noticeable, unless (5) fixes some corner-case races.

Make some small internal thinkpad-acpi changes to the hotkey subdriver code
that will make it easier to add NVRAM polling support.

Henrique de Moraes Holschuh, linux-acpi-u79uwXL29TY76Z2rM5mHXA
Older ThinkPad models do not export some of the hot keys over the
event-based ACPI hot key interface. For these models, one has to poll
the CMOS NVRAM to check the key state at a rate faster than the expected
rate at which the user might repeatedly press the same hot key.
This patch implements this functionality for many of the hotkeys in a
transparent way: hot keys will now Just Work, and the driver knows the
best approach (events or NVRAM polling) to employ, based on the
HKEY.MHKA ACPI method.
Also, the driver can turn off the polling when there are no users for
the hot keys that need such polling.
The NVRAM-based hot keys of the A3x series that have never been
implemented by later models are not supported, to avoid changes in the
keymap of the input devices that could cause headaches in the future.
There is a Kconfig option to avoid compiling the NVRAM polling code, as
it is not very small, and unlikely to be useful on any ThinkPad newer
than a T40, X31 or R52.
This patch is based on a previous effort by Richard Hughes.

+ Some thinkpad models benefit from NVRAM polling to detect a few of
+ the hot key press events. If you know your ThinkPad model does not
+ need to do NVRAM polling to support any of the hot keys you use,
+ unselecting this option will save about 1kB of memory.
+
+ ThinkPads T40 and newer, R52 and newer, and X31 and newer are
+ unlikely to need NVRAM polling in their latest BIOS versions.
+
+ NVRAM polling can detect at most the following keys: ThinkPad/Access
+ IBM, Zoom, Switch Display (fn+F7), ThinkLight, Volume up/down/mute,
+ Brightness up/down, Display Expand (fn+F8), Hibernate (fn+F12).

+ If you are not sure, say Y here. The driver enables polling only if
+ it is strictly necessary to do so.

The NVRAM polling support for hot keys is reason enough to
bump up the version string. Do it.

Remove the header file. Private header files used by a single .c file are
in bad taste, and I know better now.

Move most subdriver-related stuff imported from the header file closer to
their subdriver code. Also, delete unneeded forward declarations.

Use a generic message on hotkey_notify to log unknown and unhandled events,
and cleanup hotkey_notify a little.
Also, document event 0x5010 (brightness changed notification) and do not
log it as an unknown event (even if we do not use it for anything right
now).

Handle some HKEY events that the firmware uses to report the reason for a
wake up, and to also notify that the system could go back to sleep (if it
woke up just to eject something from the bay, or to undock).
The driver will report the reason of the last wake up in the sysfs
attribute "wakeup_reason": 0 for "none, unknown, or standard ACPI wake up
event", 1 for "bay ejection request" and 2 for "undock request".
The firmware will also report if the operation that triggered the wake up
has been completed, by issuing an HKEY 0x3003 or 0x4003 event. If the
operation fails, no event is sent. When such a hotunplug sucessfull
notification is issued, the driver sets the attribute
"wakeup_hotunplug_complete" to 1.
While the firmware does tell us whether we are waking from a suspend or
hibernation scenario, the Linux way of hibernating makes this information
not reliable, and therefore it is not reported.
The idea is that if any of these attributes are non-zero, userspace might
want to do something at the end of the "wake up from sleep" procedures,
such as offering to send the machine back into sleep as soon as it is safe
to do so.

Fix broken locking.
cool, huh?

of course that means that they should ideally be different smaller patches.
but, Henrique, we're waxing about perfection here -- your
patch hygene is already some of the best on the list.

I will remember that one :-)

I will take that as "applied" ;-) Thanks!
I now have to decide whether I should follow my heart (indent levels with
tabs, everything else with spaces), or just decide that the kernel
hopelessly chained to tabs-as-8-spaces-only land and pipe thinkpad-acpi
entirely through unexpand to get rid of a huge ammount of checkpatch.pl
nagging...

I don't take sides on whitespace issues, but instead refer all to Lindent.
So run the driver through scripts/Lindent and see what you get.
