The .get_trend callback in struct thermal_zone_device_ops has the prototype: int (*get_trend) (struct thermal_zone_device *, int, enum thermal_trend *); whereas the .get_trend callback in struct thermal_zone_of_device_ops has: int (*get_trend)(void *, long *); Streamline both prototypes and add the trip argument to the OF callback aswell and use enum thermal_trend * instead of an integer pointer. While the OF prototype may be the better one, this should be decided at framework level and not on OF level.

This adds support for hardware-tracked trip points to the device tree thermal sensor framework. The framework supports an arbitrary number of trip points. Whenever the current temperature is updated, the trip points immediately below and above the current temperature are found. A .set_trips callback is then called with the temperatures. If there is no trip point above or below the current temperature, the passed trip temperature will be -INT_MAX or INT_MAX respectively. In this callback, the driver should program the hardware such that it is notified when either of these trip points are triggered. When a trip point is triggered, the driver should call `thermal_zone_device_update' for the respective thermal zone. This will cause the trip points to be updated again. If .set_trips is not implemented, the framework behaves as before.

The TSENS controller in 8996 family of SoCs is capable of converting the ADC code outputs to real temperature values (in decidegree Celsius). It can also be programmed to provide raw ADC code, but the secure software on 8996 programs it to provide real temperatures and also does the needed calibrations. We check the valid bit to ensure valid data is read by the AHB master. And the spec recommends the below algorithm to read data 3 consecutive times, which takes care of the worst case delay taken to propagate the updated data to the register.

8960 family of SoCs have the TSENS device as part of GCC, hence the driver probes the virtual child device created by GCC and uses the parent to extract all DT properties and reuses the GCC regmap. Also GCC/TSENS are part of a domain thats not always ON. Hence add .suspend and .resume hooks to save and restore some of the inited register context. Also 8960 family have some of the TSENS init sequence thats required to be done by the HLOS driver (some later versions of TSENS do not export these registers to non-secure world, and hence need these initializations to be done by secure bootloaders) 8660 from the same family has just one sensor and hence some register offset/layout differences which need special handling in the driver.

TSENS is Qualcomms' thermal temperature sensor device. It supports reading temperatures from multiple thermal sensors present on various QCOM SoCs. Calibration data is generally read from a non-volatile memory (eeprom) device. Add a skeleton driver with all the necessary abstractions so a variety of qcom device families which support TSENS can add driver extensions. Also add the required device tree bindings which can be used to describe the TSENS device in DT.

In commit 8ead9dd5 ("devpts: more pty driver interface cleanups") I made devpts_get_priv() just return the dentry->fs_data directly. And because I thought it wouldn't happen, I added a warning if you ever saw a pts node that wasn't on devpts. And no, that warning never triggered under any actual real use, but you can trigger it by creating nonsensical pts nodes by hand. So just revert the warning, and make devpts_get_priv() return NULL for that case like it used to.

Commit e647b532 ("ACPI: Add early device probing infrastructure") introduced code that allows inserting driver specific struct acpi_probe_entry probe entries into ACPI linker sections (one per-subsystem, eg irqchip, clocksource) that are then walked to retrieve the data and function hooks required to probe the respective kernel components. Probing for all entries in a section is triggered through the __acpi_probe_device_table() function, that in turn, according to the table ID a given probe entry reports parses the table with the function retrieved from the respective section structures (ie struct acpi_probe_entry). Owing to the current ACPI table parsing implementation, the __acpi_probe_device_table() function has to share global variables with the acpi_match_madt() function, so in order to guarantee mutual exclusion locking is required between the two functions. Current kernel code implements the locking through the acpi_probe_lock spinlock; this has the side effect of requiring all code called within the lock (ie struct acpi_probe_entry.probe_{table/subtbl} hooks) not to sleep. However, kernel subsystems that make use of the early probing infrastructure are relying on kernel APIs that may sleep (eg irq_domain_alloc_fwnode(), among others) in the function calls pointed at by struct acpi_probe_entry.{probe_table/subtbl} entries (eg gic_v2_acpi_init()), which is a bug. Since __acpi_probe_device_table() is called from context that is allowed to sleep the acpi_probe_lock spinlock can be replaced with a mutex; this fixes the issue whilst still guaranteeing mutual exclusion.

The stub macro was never used since all kernel code that defines ACPI_DECLARE_PROBE_ENTRY entries is currently guarded within CONFIG_ACPI; it contains a typo that should be nonetheless fixed.

Łukasz Daniluk reported that on a RHEL kernel that his machine would lock up after enabling function tracer. I asked him to bisect the functions within available_filter_functions, which he did and it came down to three: _paravirt_nop(), _paravirt_ident_32() and _paravirt_ident_64() It was found that this is only an issue when noreplace-paravirt is added to the kernel command line. This means that those functions are most likely called within critical sections of the funtion tracer, and must not be traced. In newer kenels _paravirt_nop() is defined within gcc asm(), and is no longer an issue. But both _paravirt_ident_{32,64}() causes the following splat when they are traced: mm/pgtable-generic.c:33: bad pmd ffff8800d2435150(0000000001d00054) mm/pgtable-generic.c:33: bad pmd ffff8800d3624190(0000000001d00070) mm/pgtable-generic.c:33: bad pmd ffff8800d36a5110(0000000001d00054) mm/pgtable-generic.c:33: bad pmd ffff880118eb1450(0000000001d00054) NMI watchdog: BUG: soft lockup - CPU#2 stuck for 22s!

Pull overlayfs fixes from Miklos Szeredi: "Most of this is regression fixes for posix acl behavior introduced in 4.8-rc1 (these were caught by the pjd-fstest suite). The are also miscellaneous fixes marked as stable material and cleanups. Other than overlayfs code, it touches <linux/fs.h> to add a constant with which to disable posix acl caching. No changes needed to the actual caching code, it automatically does the right thing, although later we may want to optimize this case.

Changes to make the resume from cpu_suspend() code behave more like secondary boot caused debug exceptions to be unmasked early by __cpu_setup(). We then go on to restore mdscr_el1 in cpu_do_resume(), potentially taking break or watch points based on uninitialised registers. Mask debug exceptions in cpu_do_resume(), which is specific to resume from cpu_suspend(). Debug exceptions will be restored to their original state by local_dbg_restore() in cpu_suspend(), which runs after hw_breakpoint_restore() has re-initialised the other registers.

Patch 7f1d642f ("drivers/perf: arm-pmu: Fix handling of SPI lacking interrupt-affinity property") unintended also fixes perf_event support for bcm2835 which doesn't have PMU interrupts. Unfortunately this change introduce a NULL pointer dereference on bcm2835, because irq_is_percpu always expected to be called with a valid IRQ. So fix this regression by validating the IRQ before.

tick_nohz_start_idle() is prevented to be called if the idle tick can't be stopped since commit 1f3b0f82 ("tick/nohz: Optimize nohz idle enter"). As a result, after suspend/resume the host machine, full dynticks kvm guest will softlockup: NMI watchdog: BUG: soft lockup - CPU#0 stuck for 26s!

The bug is present in both guest and host kernels, and they both have cpu0's idle and iowait states issue, however, host kernel's suspend/resume path etc will touch watchdog to avoid the softlockup. - The watchdog will not be touched in tick_nohz_stop_idle path (need be touched since the scheduler stall is expected) if idle_active flags are not detected. - The idle and iowait states will not be accounted when exit idle loop (resched or interrupt) if idle start time and idle_active flags are not set. This patch fixes it by reverting commit 1f3b0f82 since can't stop idle tick doesn't mean can't be idle.
