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:
  pnpacpi: print resource shortage message only once
  PM: ACPI and APM must not be enabled at the same time
  ACPI: apply quirk_ich6_lpc_acpi to more ICH8 and ICH9
  ACPICA: fix acpi_serialize hang regression
  ACPI : Not register gsi for PCI IDE controller in legacy mode
  ACPI: Reintroduce run time configurable max_cstate for !CPU_IDLE case
  ACPI: Make sysfs interface in ACPI power optional.
  ACPI: EC: Enable boot EC before bus_scan
  increase PNP_MAX_PORT to 40 from 24
