Merge tag 'pm+acpi-4.4-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm
Pull more power management and ACPI updates from Rafael Wysocki: "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. Specifics: - 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 Bainbridge). - 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)" * tag 'pm+acpi-4.4-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: PCI: Fix OF logic in pci_dma_configure() Revert "Documentation: kernel_parameters for Intel P state driver" cpufreq: mediatek: fix build error cpufreq: intel_pstate: Add separate support for Airmont cores cpufreq: intel_pstate: Replace BYT with ATOM Revert "cpufreq: intel_pstate: Use ACPI perf configuration" Revert "cpufreq: intel_pstate: Avoid calculation for max/min" ACPI-EC: Drop unnecessary check made before calling acpi_ec_delete_query() Revert "ACPI / SBS: Add 5 us delay to fix SBS hangs on MacBook" ACPI / SMBus: Fix boot stalls / high CPU caused by reentrant code PM / wakeirq: check that wake IRQ is valid before accepting it ACPI / CPPC: Use h/w reduced version of the PCCT structure x86: remove unused definition of MSR_NHM_PLATFORM_INFO tools/power turbostat: use new name for MSR_PLATFORM_INFO
