Pull asm-generic updates from Arnd Bergmann: "There are only three patches this time, most other changes to files in include/asm-generic tend to go through the tree of whoever depends on the change. Two patches are cleanups for stuff that is no longer needed, the main change is to adapt the generic version of BUG_ON() for CONFIG_BUG=n to make it behave consistently with BUG(). This avoids undefined behavior along with a number of warnings about that undefined behavior in randconfig builds when we keep going on after hitting a BUG_ON()" * tag 'asm-generic-4.6' of git://git.kernel.org/pub/scm/linux/kernel/git/arnd/asm-generic: asm-generic: remove old nonatomic-io wrapper files asm-generic: default BUG_ON(x) to if(x)BUG() asm-generic: page.h: Remove useless get_user_page and free_user_page

Pull more power management and ACPI updates from Rafael Wysocki: "The second batch of power management and ACPI updates for v4.6. Included are fixups on top of the previous PM/ACPI pull request and other material that didn't make into it but still should go into 4.6. Among other things, there's a fix for an intel_pstate driver issue uncovered by recent cpufreq changes, a workaround for a boot hang on Skylake-H related to the handling of deep C-states by the platform and a PCI/ACPI fix for the handling of IO port resources on non-x86 architectures plus some new device IDs and similar. Specifics: - Fix for an intel_pstate driver issue related to the handling of MSR updates uncovered by the recent cpufreq rework (Rafael Wysocki). - cpufreq core cleanups related to starting governors and frequency synchronization during resume from system suspend and a locking fix for cpufreq_quick_get() (Rafael Wysocki, Richard Cochran). - acpi-cpufreq and powernv cpufreq driver updates (Jisheng Zhang, Michael Neuling, Richard Cochran, Shilpasri Bhat). - intel_idle driver update preventing some Skylake-H systems from hanging during initialization by disabling deep C-states mishandled by the platform in the problematic configurations (Len Brown). - Intel Xeon Phi Processor x200 support for intel_idle (Dasaratharaman Chandramouli). - cpuidle menu governor updates to make it always honor PM QoS latency constraints (and prevent C1 from being used as the fallback C-state on x86 when they are set below its exit latency) and to restore the previous behavior to fall back to C1 if the next timer event is set far enough in the future that was changed in 4.4 which led to an energy consumption regression (Rik van Riel, Rafael Wysocki). - New device ID for a future AMD UART controller in the ACPI driver for AMD SoCs (Wang Hongcheng). - Rockchip rk3399 support for the rockchip-io-domain adaptive voltage scaling (AVS) driver (David Wu). - ACPI PCI resources management fix for the handling of IO space resources on architectures where the IO space is memory mapped (IA64 and ARM64) broken by the introduction of common ACPI resources parsing for PCI host bridges in 4.4 (Lorenzo Pieralisi). - Fix for the ACPI backend of the generic device properties API to make it parse non-device (data node only) children of an ACPI device correctly (Irina Tirdea). - Fixes for the handling of global suspend flags (introduced in 4.4) during hibernation and resume from it (Lukas Wunner). - Support for obtaining configuration information from Device Trees in the PM clocks framework (Jon Hunter). - ACPI _DSM helper code and devfreq framework cleanups (Colin Ian King, Geert Uytterhoeven)" * tag 'pm+acpi-4.6-rc1-2' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: (23 commits) PM / AVS: rockchip-io: add io selectors and supplies for rk3399 intel_idle: Support for Intel Xeon Phi Processor x200 Product Family intel_idle: prevent SKL-H boot failure when C8+C9+C10 enabled ACPI / PM: Runtime resume devices when waking from hibernate PM / sleep: Clear pm_suspend_global_flags upon hibernate cpufreq: governor: Always schedule work on the CPU running update cpufreq: Always update current frequency before startig governor cpufreq: Introduce cpufreq_update_current_freq() cpufreq: Introduce cpufreq_start_governor() cpufreq: powernv: Add sysfs attributes to show throttle stats cpufreq: acpi-cpufreq: make Intel/AMD MSR access, io port access static PCI: ACPI: IA64: fix IO port generic range check ACPI / util: cast data to u64 before shifting to fix sign extension cpufreq: powernv: Define per_cpu chip pointer to optimize hot-path cpuidle: menu: Fall back to polling if next timer event is near cpufreq: acpi-cpufreq: Clean up hot plug notifier callback intel_pstate: Do not call wrmsrl_on_cpu() with disabled interrupts cpufreq: Make cpufreq_quick_get() safe to call ACPI / property: fix data node parsing in acpi_get_next_subnode() ACPI / APD: Add device HID for future AMD UART controller ...

Handle the Oscillator Failure ('OF') bit from Oscillator Status register (0x1D). This bit is cleared on set_time function and is read each time the date/time is read, but only in case of XT Oscillator selection. In RC mode, this bit is always set.

The autocalibration is separated in two bits to set in Oscillator Control register (0x1c) : - OSEL bit to select the oscillator type (XT or RC). - ACAL bit to select the autocalibration type. These functionnalities are exported in sysfs entries : "oscillator" and "autocalibration". Respectively, the values are "xtal" for XT oscillator and "rc" for RC oscillator and 0 to disable the autocalibration cycle, 512 for a 512 seconds autocalibration cycle and 1024 for a cycle of 1024 seconds. Examples : Set to XT Oscillator echo xtal > /sys/class/rtc/rtc0/device/oscillator Activate an autocalibration every 512 seconds echo 512 > /sys/class/rtc/rtc0/device/autocalibration Signed-off-by: Mylène Josserand <mylene.josserand@free-electrons.com> Signed-off-by: Alexandre Belloni <alexandre.belloni@free-electrons.com>

The rv8803 has a 60µs window where it will not answer on the i2c bus. It also means there will be no ack for the communication. Make sure communication is tried multiple times when this happens (the i2c subsystem mandates -ENXIO is that case but the number of retries is host specific). The critical parts are the probe function and the alarm callback so make sure we handle the failure there.

Pull thermal updates from Zhang Rui: - Fix a regression where bogus trip points on some Lenovo laptops start to screw up thermal control after commit 81ad4276 ("Thermal: initialize thermal zone device correctly"). On these Lenovo laptops, a bogus passive trip point is reported, which is 0 degree Celsius. Without commit 81ad4276, thermal zone fails to set cooling devices to proper cooling state, which is a bug. But with commit 81ad4276 applied, the processors are always throttled on these Lenovo laptops because the current temperature is always higher than the passive trip point. Fix things to ignore such bogus trip points. (Zhang Rui) - Introduce Mediatek thermal driver. (Sascha Hauer) - Introduce devm_ versions of OF thermal sensor register API.

Currently we disable preemption in copy_to_user_page; a behaviour that we inherited from the 32-bit arm code. This was necessary for older cores without broadcast data cache maintenance, and ensured that cache lines were dirtied and cleaned by the same CPU. On these systems dirty cache line migration was not possible, so this was sufficient to guarantee coherency. On contemporary systems, cache coherence protocols permit (dirty) cache lines to migrate between CPUs as a result of speculation, prefetching, and other behaviours. To account for this, in ARMv8 data cache maintenance operations are broadcast and affect all data caches in the domain associated with the VA (i.e. ISH for kernel and user mappings). In __switch_to we ensure that tasks can be safely migrated in the middle of a maintenance sequence, using a dsb(ish) to ensure prior explicit memory accesses are observed and cache maintenance operations are completed before a task can be run on another CPU. Given the above, it is not necessary to disable preemption in copy_to_user_page. This patch removes the preempt_{disable,enable} calls, permitting preemption.

Commit 324420bf ("arm64: add support for ioremap() block mappings") added new p?d_set_huge functions which do the hard work to generate and set a correct block entry. These differ from open-coded huge page creation in the early page table code by explicitly setting the P?D_TYPE_SECT bits (which are implicitly retained by mk_sect_prot() for any valid prot), but are otherwise identical (and cannot fail on arm64). For simplicity and consistency, make use of these in the initial page table creation code.
