2021-01-07net: phy: replace mutex_is_locked with lockdep_assert_held in phylibHeiner Kallweit
Switch to lockdep_assert_held(_once), similar to what is being done in other subsystems. One advantage is that there's zero runtime overhead if lockdep support isn't enabled.

2021-01-07bcm63xx_enet: convert to build_skbSieng Piaw Liew
We can increase the efficiency of rx path by using buffers to receive packets then build SKBs around them just before passing into the network stack. In contrast, preallocating SKBs too early reduces CPU cache efficiency. Check if we're in NAPI context when refilling RX. Normally we're almost always running in NAPI context. Dispatch to napi_alloc_frag directly instead of relying on netdev_alloc_frag which does the same but with the overhead of local_bh_disable/enable. Tested on BCM6328 320 MHz and iperf3 -M 512 to measure packet/sec performance. Included netif_receive_skb_list and NET_IP_ALIGN optimizations.

2021-01-07qmi_wwan: Increase headroom for QMAP SKBsKristian Evensen
When measuring the throughput (iperf3 + TCP) while routing on a not-so-powerful device (Mediatek MT7621, 880MHz CPU), I noticed that I achieved significantly lower speeds with QMI-based modems than for example a USB LAN dongle. The CPU was saturated in all of my tests. With the dongle I got ~300 Mbit/s, while I only measured ~200 Mbit/s with the modems. All offloads, etc. were switched off for the dongle, and I configured the modems to use QMAP (16k aggregation). The tests with the dongle were performed in my local (gigabit) network, while the LTE network the modems were connected to delivers 700-800 Mbit/s. Profiling the kernel revealed the cause of the performance difference. In qmimux_rx_fixup(), an SKB is allocated for each packet contained in the URB. This SKB has too little headroom, causing the check in skb_cow() (called from ip_forward()) to fail. pskb_expand_head() is then called and the SKB is reallocated. In the output from perf, I see that a significant amount of time is spent in pskb_expand_head() + support functions. In order to ensure that the SKB has enough headroom, this commit increases the amount of memory allocated in qmimux_rx_fixup() by LL_MAX_HEADER. The reason for using LL_MAX_HEADER and not a more accurate value, is that we do not know the type of the outgoing network interface. After making this change, I achieve the same throughput with the modems as with the dongle.

2021-01-06can: flexcan: add CAN wakeup function for i.MX8QMJoakim Zhang
The System Controller Firmware (SCFW) is a low-level system function which runs on a dedicated Cortex-M core to provide power, clock, and resource management. It exists on some i.MX8 processors. e.g. i.MX8QM (QM, QP), and i.MX8QX (QXP, DX). SCU driver manages the IPC interface between host CPU and the SCU firmware running on M4. For i.MX8QM, stop mode request is controlled by System Controller Unit(SCU) firmware, this patch introduces FLEXCAN_QUIRK_SETUP_STOP_MODE_SCFW quirk for this function.

2021-01-06can: tcan4x5x: rework SPI accessMarc Kleine-Budde
This patch reworks the SPI access and fixes several probems: - tcan4x5x_regmap_gather_write(), tcan4x5x_regmap_read(): Do not place variable "addr" on stack and use it as buffer for SPI transfer. Buffers for SPI transfers must be allocated from DMA save memory. - tcan4x5x_regmap_gather_write(), tcan4x5x_regmap_read(): Halfe number of SPI transfers by using a single buffer + memcpy(). This improves the performance, especially on SPI controllers, which use interrupt based transfers. - Use "8" bits per word, not "32". This makes it possible to use this driver on SoCs like the Raspberry Pi, which SPI host controller drivers only support 8 bits per word. Note: this breaks half duplex only controllers. Support for them will be re-added in the next patch.

2021-01-05enetc: don't use macro magic for the readx_poll_timeout() callbackMichael Walle
The macro enetc_mdio_rd_reg() is just used in that particular case and has a hardcoded parameter name "mdio_priv". Define a specific function to use for readx_poll_timeout() instead.
