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
