The ACPI feature pull request for the Linux 3.5 kernel
merge window was submitted on Saturday.
The pull request for the ACPI updates was submitted by Intel's Len Brown and can be found on LKML.org
The work in the 3.5 kernel is a "gradual evolution", but no extraordinary improvements. Some of the items worth mentioning are just the thermal driver having a generic cpufreq cooling implementation, a Samsung Exynos5 thermal sensor driver, updated ACPICA to 20120420, various ACPICA improvements, initial Ivy Bridge support for the intel_idle driver, and a re-write of the Turbostat power utility for greater efficiency.
