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: (65 commits) ACPI: suppress power button event on S3 resume ACPI: resolve merge conflict between sem2mutex and processor_perflib.c ACPI: use for_each_possible_cpu() instead of for_each_cpu() ACPI: delete newly added debugging macros in processor_perflib.c ACPI: UP build fix for bugzilla-5737 Enable P-state software coordination via _PDC P-state software coordination for speedstep-centrino P-state software coordination for acpi-cpufreq P-state software coordination for ACPI core ACPI: create acpi_thermal_resume() ACPI: create acpi_fan_suspend()/acpi_fan_resume() ACPI: pass pm_message_t from acpi_device_suspend() to root_suspend() ACPI: create acpi_device_suspend()/acpi_device_resume() ACPI: replace spin_lock_irq with mutex for ec poll mode ACPI: Allow a WAN module enable/disable on a Thinkpad X60. sem2mutex: acpi, acpi_link_lock ACPI: delete unused acpi_bus_drivers_lock sem2mutex: drivers/acpi/processor_perflib.c ACPI add ia64 exports to build acpi_memhotplug as a module ACPI: asus_acpi_init(): propagate correct return value ...
