2020-01-27bnxt_en: Improve link up detection.Michael Chan
In bnxt_update_phy_setting(), ethtool_get_link_ksettings() and bnxt_disable_an_for_lpbk(), we inconsistently use netif_carrier_ok() to determine link. Instead, we should use bp->link_info.link_up which has the true link state. The netif_carrier state may be off during self-test and while the device is being reset and may not always reflect the true link state. By always using bp->link_info.link_up, the code is now more consistent and more correct. Some unnecessary link toggles are now prevented with this patch.

2020-01-27bpf, xdp: Remove no longer required rcu_read_{un}lock()John Fastabend
Now that we depend on rcu_call() and synchronize_rcu() to also wait for preempt_disabled region to complete the rcu read critical section in __dev_map_flush() is no longer required. Except in a few special cases in drivers that need it for other reasons. These originally ensured the map reference was safe while a map was also being free'd. And additionally that bpf program updates via ndo_bpf did not happen while flush updates were in flight. But flush by new rules can only be called from preempt-disabled NAPI context. The synchronize_rcu from the map free path and the rcu_call from the delete path will ensure the reference there is safe. So lets remove the rcu_read_lock and rcu_read_unlock pair to avoid any confusion around how this is being protected. If the rcu_read_lock was required it would mean errors in the above logic and the original patch would also be wrong. Now that we have done above we put the rcu_read_lock in the driver code where it is needed in a driver dependent way. I think this helps readability of the code so we know where and why we are taking read locks. Most drivers will not need rcu_read_locks here and further XDP drivers already have rcu_read_locks in their code paths for reading xdp programs on RX side so this makes it symmetric where we don't have half of rcu critical sections define in driver and the other half in devmap.

2020-01-27bpf, xdp: virtio_net use access ptr macro for xdp enable checkJohn Fastabend
virtio_net currently relies on rcu critical section to access the xdp program in its xdp_xmit handler. However, the pointer to the xdp program is only used to do a NULL pointer comparison to determine if xdp is enabled or not. Use rcu_access_pointer() instead of rcu_dereference() to reflect this. Then later when we drop rcu_read critical section virtio_net will not need in special handling.

2020-01-27thermal: generic-adc: silence "no lookup table" on deferred probeMartin Blumenstingl
A "generic-adc-thermal" without "temperature-lookup-table" is perfectly valid since commit d36e2fa0253875 ("thermal: generic-adc: make lookup table optional"). On deferred probe the message "no lookup table, assuming DAC channel returns milliCelcius" is still logged. Prevent this message on deferred probe of the IIO channel by first looking up the IIO channel.

2020-01-27thermal/drivers/cpu_cooling: Introduce the cpu idle cooling driverDaniel Lezcano
The cpu idle cooling device offers a new method to cool down a CPU by injecting idle cycles at runtime. It has some similarities with the intel power clamp driver but it is actually designed to be more generic and relying on the idle injection powercap framework. The idle injection duration is fixed while the running duration is variable. That allows to have control on the device reactivity for the user experience. An idle state powering down the CPU or the cluster will allow to drop the static leakage, thus restoring the heat capacity of the SoC. It can be set with a trip point between the hot and the critical points, giving the opportunity to prevent a hard reset of the system when the cpufreq cooling fails to cool down the CPU. With more sophisticated boards having a per core sensor, the idle cooling device allows to cool down a single core without throttling the compute capacity of several cpus belonging to the same clock line, so it could be used in collaboration with the cpufreq cooling device.

The next changes will add a new way to cool down a CPU by injecting idle cycles. With the current configuration, a CPU cooling device is the cpufreq cooling device. As we want to add a new CPU cooling device, let's convert the CPU cooling to a choice giving a list of CPU cooling devices. At this point, there is obviously only one CPU cooling device.
