Please pull from
to receive power management and ACPI material for v4.4-rc2 with
top-most commit a3767e3c9da514e63e898772b72b932f9eb3b062
Merge branches 'acpi-smbus', 'acpi-ec' and 'acpi-pci'
on top of commit 8005c49d9aea74d382f474ce11afbbc7d7130bec
These are mostly fixes and cleanups (ACPI core, PM core, cpufreq,
ACPI EC driver, device properties) including three reverts of recent
intel_pstate driver commits due to a regression introduced by one
of them plus support for Atom Airmont cores in intel_pstate (which
really boils down to adding new frequency tables for Airmont) and
additional turbostat updates.
- Revert three recent intel_pstate driver commits one of which
introduced a regression and the remaining two depend on the
problematic one (Rafael Wysocki).
- Fix breakage related to the recently introduced ACPI _CCA object
support in the PCI DMA setup code (Suravee Suthikulpanit).
- Fix up the recently introduced ACPI CPPC support to only
use the hardware-reduced version of the PCCT structure as
the only architecture to support it (ARM64) will only use
hardware-reduced ACPI anyway (Ashwin Chaugule).
- Fix a cpufreq mediatek driver build problem (Arnd Bergmann).
- Fix the SMBus transaction handling implementation in the ACPI
core to avoid re-entrant calls to wait_event_timeout() which
makes intermittent boot stalls related to the Smart Battery
Subsystem initialization go away and revert a workaround of
another problem with the same underlying root cause (Chris
- Fix the generic wakeup interrupts framework to avoid using
invalid IRQ numbers (Dmitry Torokhov).
- Remove a redundant check from the ACPI EC driver (Markus Elfring).
- Modify the intel_pstate driver so it can support more Atom flavors
than just one (Baytrail) and add support for Atom Airmont cores
(which require new freqnency tables) to it (Philippe Longepe).
- Clean up MSR-related symbols in turbostat (Len Brown).
