struct bin_attribute * is needed in bin_attribute ->read()/->write()
now. Incidentally, could people please run the fscking compiler
before and after applying their patch and compare the build logs?
That (and many, many other) would be caught immediately.

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.

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.

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.

/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.

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.

Testing the wrong bit caused kvm not to disable nx on the guest when it is
disabled on the host (an mmu optimization relies on the nx bits being the
same in the guest and host).
This allows Windows to boot when nx is disabled on te host (e.g. when
host pae is disabled).

This avoids use of the kernel-internal "xtime" variable directly outside
of the actual time-related functions. Instead, use the helper functions
that we already have available to us.
This doesn't actually change any behaviour, but this will allow us to
fix the fact that "xtime" isn't updated very often with CONFIG_NO_HZ
(because much of the realtime information is maintained as separate
offsets to 'xtime'), which has caused interfaces that use xtime directly
to get a time that is out of sync with the real-time clock by up to a
third of a second or so.

ACPI implementations in several TOSHIBA laptops are weird and burn cpu
cycles for tens of seconds while trying to suspend if the PCI device
for the ATA controller is disabled when the ACPI suspend is called.
This patch uses DMI to match those machines and bypass device disable
on those machines during suspend. As the device needs to be put into
enabled state on resume without affecting PCI enable count, matching
resume callback uses __pci_reenable_device().
This bug is reported in bugzilla bug 7780.

Some odd ACPI implementations choke if certain controller is disabled
when ACPI suspend is invoked but we still need to make sure the PCI
device is enabled during resume. Simply using pci_enable_device()
unbalances device enable count. Export __pci_reenable_device().
