Merge branch 'release' of git://git.kernel.org/pub/scm/linux/kernel/git/lenb/linux
Pull ACPI & power management update from Len Brown: "Re-write of the turbostat tool. lower overhead was necessary for measuring very large system when they are very idle. IVB support in intel_idle It's what I run on my IVB, others should be able to also:-) ACPICA core update We have found some bugs due to divergence between Linux and the upstream ACPICA base. Most of these patches are to reduce that divergence to reduce the risk of future bugs. Some cpuidle updates, mostly for non-Intel More will be coming, as they depend on this part. Some thermal management changes needed by non-ACPI systems. Some _OST (OS Status Indication) updates for hot ACPI hot-plug." * 'release' of git://git.kernel.org/pub/scm/linux/kernel/git/lenb/linux: (51 commits) Thermal: Documentation update Thermal: Add Hysteresis attributes Thermal: Make Thermal trip points writeable ACPI/AC: prevent OOPS on some boxes due to missing check power_supply_register() return value check tools/power: turbostat: fix large c1% issue tools/power: turbostat v2 - re-write for efficiency ACPICA: Update to version 20120711 ACPICA: AcpiSrc: Fix some translation issues for Linux conversion ACPICA: Update header files copyrights to 2012 ACPICA: Add new ACPI table load/unload external interfaces ACPICA: Split file: tbxface.c -> tbxfload.c ACPICA: Add PCC address space to space ID decode function ACPICA: Fix some comment fields ACPICA: Table manager: deploy new firmware error/warning interfaces ACPICA: Add new interfaces for BIOS(firmware) errors and warnings ACPICA: Split exception code utilities to a new file, utexcep.c ACPI: acpi_pad: tune round_robin_time ACPICA: Update to version 20120620 ACPICA: Add support for implicit notify on multiple devices ACPICA: Update comments; no functional change ...
