When the LL Privacy support is available, then as part of enabling or disabling passive background scanning, it is required to set up the controller based address resolution as well. Since only passive background scanning is utilizing the whitelist, the address resolution is now bound to the whitelist and passive background scanning. All other resolution can be easily done by the host stack.

2020-07-30driver core: add deferring probe reason to devices_deferred propertyAndrzej Hajda
/sys/kernel/debug/devices_deferred property contains list of deferred devices. This list does not contain reason why the driver deferred probe, the patch improves it. The natural place to set the reason is dev_err_probe function introduced recently, ie. if dev_err_probe will be called with -EPROBE_DEFER instead of printk the message will be attached to a deferred device and printed when user reads devices_deferred property.

2020-07-30driver core: add device probe log helperAndrzej Hajda
During probe every time driver gets resource it should usually check for error printk some message if it is not -EPROBE_DEFER and return the error. This pattern is simple but requires adding few lines after any resource acquisition code, as a result it is often omitted or implemented only partially. dev_err_probe helps to replace such code sequences with simple call, so code: if (err != -EPROBE_DEFER) dev_err(dev, ...); return err; becomes: return dev_err_probe(dev, err, ...); Signed-off-by: Andrzej Hajda <a.hajda@samsung.com> Reviewed-by: Rafael J.

2020-07-30driver core: Avoid binding drivers to dead devicesLukas Wunner
Commit 3451a495ef24 ("driver core: Establish order of operations for device_add and device_del via bitflag") sought to prevent asynchronous driver binding to a device which is being removed. It added a per-device "dead" flag which is checked in the following code paths: * asynchronous binding in __driver_attach_async_helper() * synchronous binding in device_driver_attach() * asynchronous binding in __device_attach_async_helper() It did *not* check the flag upon: * synchronous binding in __device_attach() However __device_attach() may also be called asynchronously from: deferred_probe_work_func() bus_probe_device() device_initial_probe() __device_attach() So if the commit's intention was to check the "dead" flag in all asynchronous code paths, then a check is also necessary in __device_attach(). Add the missing check.

Register a power supply charger, whose online state depends on whether the USB role is set to device or not. This is useful when the USB role is the only way to know if the device is charging from USB. The API is the standard power supply charger API, you get a /sys/class/power_supply/xxx/online node which tells you the state of the charger.

2020-07-30cpufreq: make schedutil the default for arm and arm64Valentin Schneider
schedutil is already a hard-requirement for EAS, which has lead to making it default on arm (when CONFIG_BIG_LITTLE), see: commit 8fdcca8e254a ("cpufreq: Select schedutil when using big.LITTLE") One thing worth pointing out is that schedutil isn't only relevant for asymmetric CPU capacity systems; for instance, schedutil is the only governor that honours util-clamp performance requests. Another good example of this is x86 switching to using it by default in: commit a00ec3874e7d ("cpufreq: intel_pstate: Select schedutil as the default governor") Arguably it should be made the default for all architectures, but it seems better to wait for them to also gain frequency invariance powers.

Commit 0c868627e617e43a295d8 (cpufreq: dt: Allow platform specific intermediate callbacks) added two function pointers to the struct cpufreq_dt_platform_data. However, armada37xx_cpufreq_driver_init() has this struct (pdata) located on the stack and uses only "suspend" and "resume" fields. So these newly added "get_intermediate" and "target_intermediate" pointers are uninitialized and contain arbitrary non-null values, causing all kinds of trouble.

This is also bogus, as keepalive messages (a single 0xff byte), though not needed with TCP encapsulation, should be allowed.

2020-07-30powerpc: fix function annotations to avoid section mismatch warnings with gcc-10Vladis Dronov
Certain warnings are emitted for powerpc code when building with a gcc-10 toolset: WARNING: modpost: vmlinux.o(.text.unlikely+0x377c): Section mismatch in reference from the function remove_pmd_table() to the function .meminit.text:split_kernel_mapping() The function remove_pmd_table() references the function __meminit split_kernel_mapping(). This is often because remove_pmd_table lacks a __meminit annotation or the annotation of split_kernel_mapping is wrong. Add the appropriate __init and __meminit annotations to make modpost not complain. In all the cases there are just a single callsite from another __init or __meminit function: __meminit remove_pagetable() -> remove_pud_table() -> remove_pmd_table() __init prom_init() -> setup_secure_guest() __init xive_spapr_init() -> xive_spapr_disabled() Signed-off-by: Vladis Dronov <vdronov@redhat.com> Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> Link: https://lore.kernel.org/r/20200729133741.62789-1-vdronov@redhat.com
