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: (23 commits) ACPI PCI hotplug: harden against panic regression ACPI: rename main.c to sleep.c dell-laptop: move to drivers/platform/x86/ from drivers/misc/ eeepc-laptop: enable Bluetooth ACPI details ACPI: fix ACPI_FADT_S4_RTC_WAKE comment kprobes: check CONFIG_FREEZER instead of CONFIG_PM PM: Fix freezer compilation if PM_SLEEP is unset thermal fixup for broken BIOS which has invalid trip points. ACPI: EC: Don't trust ECDT tables from ASUS ACPI: EC: Limit workaround for ASUS notebooks even more ACPI: thinkpad-acpi: bump up version to 0.22 ACPI: thinkpad-acpi: handle HKEY event 6030 ACPI: thinkpad-acpi: clean-up fan subdriver quirk ACPI: thinkpad-acpi: start the event hunt season ACPI: thinkpad-acpi: handle HKEY thermal and battery alarms ACPI: thinkpad-acpi: clean up hotkey_notify() ACPI: thinkpad-acpi: use killable instead of interruptible mutexes ACPI: thinkpad-acpi: add UWB radio support ACPI: thinkpad-acpi: preserve radio state across shutdown ACPI: thinkpad-acpi: resume with radios disabled ...
