2020-07-03arm64: Add KRYO4XX silver CPU cores to erratum list 1530923 and 1024718Sai Prakash Ranjan
KRYO4XX silver/LITTLE CPU cores with revision r1p0 are affected by erratum 1530923 and 1024718, so add them to the respective list. The variant and revision bits are implementation defined and are different from the their Cortex CPU counterparts on which they are based on, i.e., r1p0 is equivalent to rdpe.

2020-06-30net: phy: don't abuse devres in devm_mdiobus_register()Bartosz Golaszewski
We currently have two managed helpers for mdiobus - devm_mdiobus_alloc() and devm_mdiobus_register(). The idea behind devres is that the release callback releases whatever resource the devm function allocates. In the mdiobus case however there's no devres associated with the device by devm_mdiobus_register(). Instead the release callback for devm_mdiobus_alloc(): _devm_mdiobus_free() unregisters the device if it is marked as managed. This all seems wrong. The managed structure shouldn't need to know or care about whether it's managed or not - and this is the case now for struct mii_bus. The devres wrapper should be opaque to the managed resource. This changeset makes devm_mdiobus_alloc() and devm_mdiobus_register() conform to common devres standards: devm_mdiobus_alloc() allocates a devres structure and registers a callback that will call mdiobus_free(). __devm_mdiobus_register() allocated another devres and registers a callback that will unregister the bus.

2020-06-30dt-bindings: copy process-schema-examples.yaml to process-schema.yamlMasahiro Yamada
There are two processed schema files: - processed-schema-examples.yaml Used for 'make dt_binding_check'. This is always a full schema. - processed-schema.yaml Used for 'make dtbs_check'. This may be a full schema, or a smaller subset if DT_SCHEMA_FILES is given by a user. If DT_SCHEMA_FILES is not specified, they are the same. You can copy the former to the latter instead of running dt-mk-schema twice. This saves the cpu time a lot when you do 'make dt_binding_check dtbs_check' because building the full schema takes a couple of seconds. If DT_SCHEMA_FILES is specified, processed-schema.yaml is generated based on the specified yaml files.

The Channel/RQ is selected according to the socket's rxq index. A new TLS-RX workqueue is used to allow asynchronous addition of steering rules, out of the NAPI context. It will be also used in a downstream patch in the resync procedure. Feature is OFF by default. Can be turned on by: $ ethtool -K <if> tls-hw-rx-offload on 4) Added mlx5 kTLS sw stats and new counters are documented in Documentation/networking/tls-offload.rst rx_tls_ctx - number of TLS RX HW offload contexts added to device for decryption. rx_tls_ooo - number of RX packets which were part of a TLS stream but did not arrive in the expected order and triggered the resync procedure. rx_tls_del - number of TLS RX HW offload contexts deleted from device (connection has finished). rx_tls_err - number of RX packets which were part of a TLS stream but were not decrypted due to unexpected error in the state machine. 5) Asynchronous RX resync a. The NIC driver indicates that it would like to resync on some TLS record within the received packet (P), but the driver does not know (yet) which of the TLS records within the packet. At this stage, the NIC driver will query the device to find the exact TCP sequence for resync (tcpsn), however, the driver does not wait for the device to provide the response. b. Eventually, the device responds, and the driver provides the tcpsn within the resync packet to KTLS. Now, KTLS can check the tcpsn against any processed TLS records within packet P, and also against any record that is processed in the future within packet P. The asynchronous resync path simplifies the device driver, as it can save bits on the packet completion (32-bit TCP sequence), and pass this information on an asynchronous command instead.

2020-06-26docs: networking: reorganize driver documentation againJakub Kicinski
Organize driver documentation by device type. Most documents have fairly verbose yet uninformative names, so let users first select a well defined device type, and then search for a particular driver. While at it rename the section from Vendor drivers to Hardware drivers. This seems more accurate, besides people sometimes refer to out-of-tree drivers as vendor drivers.

2020-06-26doc: THP CoW fault no longer allocate THPYang Shi
Since commit 3917c80280c9 ("thp: change CoW semantics for anon-THP"), THP CoW page fault is rewritten. Now it just splits pmd then fallback to base page fault, it doesn't try to allocate THP anymore. So it is no longer counted in THP_FAULT_ALLOC. Remove the obsolete statement in documentation about THP CoW allocation to avoid confusion.

2020-06-26wilc1000: move wilc driver out of stagingAjay Singh
WILC1000 is an IEEE 802.11 b/g/n IoT link controller module. The WILC1000 connects to Microchip AVR/SMART MCUs, SMART MPUs, and other processors with minimal resource requirements with a simple SPI/SDIO-to-Wi-Fi interface. WILC1000 driver has been part of staging for few years. With contributions from the community, it has improved significantly. Full driver review has helped in achieving the current state. The details for those reviews are captured in 1 & 2.
