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: drivers/acpi: elide a non-zero test on a result that is never 0
  pnpacpi: reduce printk severity for "pnpacpi: exceeded the max number of ..."
  cpuidle: fix 100% C0 statistics regression
  cpuidle: fix cpuidle time and usage overflow
  ACPI: fix mis-merge -- invoke acpi_unlazy_tlb() only on C3 entry
  ACPI: fix a regression of ACPI device driver autoloading
  ACPI: SBS: remove typo from sbchc.c
