Merge branch 'release' of git://git.kernel.org/pub/scm/linux/kernel/git/lenb/linux-acpi-2.6

* 'release' of git://git.kernel.org/pub/scm/linux/kernel/git/lenb/linux-acpi-2.6:
  ACPI: Kconfig: remove CONFIG_ACPI_SLEEP from source
  ACPI: quiet ACPI Exceptions due to no _PTC or _TSS
  ACPI: Remove references to ACPI_STATE_S2 from acpi_pm_enter
  ACPI: Kconfig: always enable CONFIG_ACPI_SLEEP on X86
  ACPI: Kconfig: fold /proc/acpi/sleep under CONFIG_ACPI_PROCFS
  ACPI: Kconfig: CONFIG_ACPI_PROCFS now defaults to N
  ACPI: autoload modules - Create __mod_acpi_device_table symbol for all ACPI drivers
  ACPI: autoload modules - Create ACPI alias interface
  ACPI: autoload modules - ACPICA modifications
  ACPI: asus-laptop: Fix failure exits
  ACPI: fix oops due to typo in new throttling code
  ACPI: ignore _PSx method for hotplugable PCI devices
  ACPI: Use ACPI methods to select PCI device suspend state
  ACPI, PNP: hook ACPI D-state to PNP suspend/resume
  ACPI: Add acpi_pm_device_sleep_state helper routine
  ACPI: Implement the set_target() callback from pm_ops

-          This option adds support for ACPI suspend states. 
-
-          With this option, you will be able to put the system "to sleep". 
-          Sleep states are low power states for the system and devices. All
-          of the system operating state is saved to either memory or disk
-          (depending on the state), to allow the system to resume operation
-          quickly at your request.
-
-          Although this option sounds really nifty, barely any of the device
-          drivers have been converted to the new driver model and hence few
-          have proper power management support. 
-
-          This option is not recommended for anyone except those doing driver
-          power management development.

-          The Procfs interface for ACPI is made optional for backward compatibility.
-          As the same functions are duplicated in the sysfs interface
-          and this proc interface will be removed some time later,
-          it's marked as deprecated.
-          ( /proc/acpi/debug_layer && debug_level are deprecated by
-            /sys/module/acpi/parameters/debug_layer && debug_level.
-            /proc/acpi/info is deprecated by
-            /sys/module/acpi/parameters/acpica_version )
+          For backwards compatibility, this option allows
+          depricated /proc/acpi/ files to exist, even when
+          they have been replaced by functions in /sys.
+          The deprecated files (and their replacements) include:
+
+          /proc/acpi/sleep (/sys/power/state)
+          /proc/acpi/info (/sys/modules/acpi/parameters/acpica_version)
+          /proc/acpi/dsdt (/sys/firmware/acpi/tables/DSDT)

+          /proc/acpi/debug_level (/sys/module/acpi/parameters/debug_level)
+
+          This option has no effect on /proc/acpi/ files
+          and functions which do not yet exist in /sys.
+
+          Say N to delete /proc/acpi/ files that have moved to /sys/
