Hi Linus,

please pull from:

git://git.kernel.org/pub/scm/linux/kernel/git/lenb/linux-acpi-2.6.git release

Fixes regressions -- a build failure, an oops, some dmesg spam.
Also fixes some D-state issues and adds ACPI module auto-loading.
Yes, I'd hoped to get the last two in before rc1.
I'm hopeful that a couple-days into rc2 is sufficiently early for them.

This will update the files shown below.

thanks!

-Len

ps. individual patches are available on linux-acpi@xxxxxxxxxxxxxxx

ACPI: Kconfig: remove CONFIG_ACPI_SLEEP from source

As it was a synonym for (CONFIG_ACPI && CONFIG_X86),
the ifdefs for it were more clutter than they were worth.

For ia64, just add a few stubs in anticipation of future
S3 or S4 support.

These methods are optional, so Linux should not
alarm users when they are not found.

ACPI: Kconfig: always enable CONFIG_ACPI_SLEEP on X86

The SMP dependency on HOTPLUG_CPU and SUSPEND_SMP
caused more harm than good -- making ACPI sleep
support vanish for configs missing those options.
So simply select them on the (ACPI && SMP && X86) systems
that need them.

Also, remove the prompt for ACPI_SLEEP,
virtually nobody (intentionally) enables ACPI without it.

ACPI: Kconfig: fold /proc/acpi/sleep under CONFIG_ACPI_PROCFS

/proc/acpi/sleep has had its own "default n" option,
ACPI_SLEEP_PROC_SLEEP, for many months.
Time to delete ACPI_SLEEP_PROC_SLEEP.

Users that still need /proc/acpi/sleep can still get it
along with the other deprecated /proc/acpi files
by enabling CONFIG_ACPI_PROCFS.

Also delete ACPI_SLEEP_PROC_FS, which was an umbrella
for /proc/acpi/sleep, wakeup, alarm, because it was
effectively just a synonym for ACPI_SLEEP.

ACPI: autoload modules - Create ACPI alias interface

Modify modpost (file2alias.c) to add acpi*:XYZ0001: alias in modules.alias
like:
grep acpi /lib/modules/2.6.22-rc4-default/modules.alias
alias acpi*:SNY5001:* sony_laptop
alias acpi*:SNY6001:* sony_laptop
for e.g. the sony_laptop module.
This module matches against all ACPI devices with a HID or CID of SNY5001
or SNY6001

Export an uevent and modalias sysfs file containing the string:
[MODALIAS=]acpi:PNP0C0C:
additional CIDs are concatenated at the end.

ACPI: asus-laptop: Fix failure exits

> Subject : drivers/misc/asus-laptop.c:*: error: 'struct led_classdev' has no member named 'class_dev'
> References : http://lkml.org/lkml/2007/7/22/299
> Submitter : Gabriel C <nix.or.die@xxxxxxxxxxxxxx>

Fallout from f8a7c6fe14f556ca8eeddce258cb21392d0c3a2f. However, looking
at it shows that checks done in ASUS_LED_UNREGISTER() can't trigger
at all (we never get to asus_led_exit() if registration fails) and
if that registration fails, we actually leak stuff. IOW, it's worse
than just replacing class_dev with dev in there - the tests themselves
had been papering over the lousy cleanup logics.

ACPI: Implement the set_target() callback from pm_ops

In the future some drivers may need to use ACPI to determine the low power
states in which to place their devices, but to provide the drivers with this
information the ACPI core needs to know what sleep state the system is going to
enter. Namely, the device's state should not be too high power for given system
sleep state and, if the device is supposed to be able to wake up the system, its
state should not be too low power for the wake up to be possible). For this
purpose, the ACPI core needs to implement the set_target() method in 'struct
pm_ops' and store the target system sleep state passed by the PM core in a
variable.
