git://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux Pull powerpc updates from Michael Ellerman: "Highlights include: - Support for direct mapped LPC on POWER9, giving Linux direct access to devices that may be on there such as a UART. - Memory hotplug support for the Power9 Radix MMU. - Add new AUX vectors describing the processor's cache geometry, to be used by glibc. - The ability for a guest to ask the hypervisor to resize the guest's hash table, and in addition support for doing so automatically when memory is hotplugged into/out-of the guest. This allows the hash table to be sized based on the current memory usage of the guest, rather than the maximum possible memory usage. - Implementation of optprobes (kprobe optimisation) for powerpc. In addition there's the topic branch shared with the KVM tree, which includes support for guests to use the Radix MMU on Power9.

git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl Pull pin control updates from Linus Walleij: "Pin control bulk changes for the v4.11 kernel cycle. Core changes: - Switch the generic pin config argument from 16 to 24 bits, only use 8 bits for the configuration type. We might need to encode more information about a certain setting than we need to encode different generic settings. - Add a cross-talk API to the pin control GPIO back-end, utilizing pinctrl_gpio_set_config() from GPIO drivers that want to set up a certain pin configuration in the back-end. This also includes the .set_config() refactoring of the GPIO chips, so that they pass a generic configuration for things like debouncing and single ended (typically open drain). This change has also been merged in an immutable branch to the GPIO tree. - Take hogs with a delayed work, so that we finalize probing a pin controller before trying to get any hogs. - For pin controllers putting all group and function definitions into the device tree, we now have generic code to deal with this and it is used in two drivers so far. - Simplifications of the pin request conflict check. - Make dt_free_map() optional. Updates to drivers: - pinctrl-single now use the generic helpers to generate dynamic group and function tables from the device tree. - Texas Instruments IOdelay configuration driver add-on to pinctrl-single. - i.MX: use radix trees to store groups and functions, use the new generic group and function helpers to manage them. - Intel: add support for hardware debouncing and 1K pull-down. New subdriver for the Gemini Lake SoC. - Renesas SH-PFC: drive strength and bias support, CAN bus muxing, MSIOF, SDHI, HSCIF for r8a7796. Gyro-ADC supporton r8a7791. - Aspeed: use syscon cross-dependencies to set up related bits in the LPC host controller and display controller. - Aspeed: finalize G4 and G5 support. Fix mux configuration on GPIOs. Add banks Y, Z, AA, AB and AC. - AMD: support additional GPIO. - STM32: set this controller to strict muxing mode. STM32H743 MCU support. - Allwinner sunxi: deep simplifications on how to support subvariants of SoCs without adding to much SoC-specific data for each subvariant, especially for sun5i variants. New driver for V3s SoCs. New driver for the H5 SoC. Support A31/A31s variants with the new variant framework. - Mvebu: simplifications to use a MMIO and regmap abstraction. New subdrivers for the 98DX3236, 98DX5241 SoCs. - Samsung Exynos: delete Exynos4415 support. Add crosstalk to the SoC driver to access regmaps. Add infrastructure for pin-bank retention control. Clean out the pin retention control from arch/arm/mach-exynos and arch/arm/mach-s5p and put it properly in the Samsung pin control driver(s). - Meson: add HDMI HPD/DDC pins.

2017-02-22HID: rmi: fallback to generic/multitouch if hid-rmi is not builtJiri Kosina
Commit 279967a65b32 ("HID: rmi: Handle all Synaptics touchpads using hid-rmi") unconditionally switches over handling of all Synaptics touchpads to hid-rmi (to make use of extended features of the HW); in case CONFIG_HID_RMI is disabled though this renders the touchpad unusable, as the HID_DEVICE(HID_BUS_ANY, HID_GROUP_RMI, HID_ANY_ID, HID_ANY_ID) match doesn't exist and generic/multitouch doesn't bind to it either (due to hid group mismatch). Fix this by switching over to hid-rmi only if it has been actually built.

This reverts commit f2593cb1b29185d38db706cbcbe22ed538720ae1. Paul reported that this patch with older board-2.bin ath10k initialisation fails on Dell XPS 13: ath10k_pci 0000:3a:00.0: failed to fetch board data for bus=pci,vendor=168c, device=003e,subsystem-vendor=1a56,subsystem-device=1535,variant=RV_0520 from ath10k/QCA6174/hw3.0/board-2.bin The reason is that the older board-2.bin does not have the variant version of the image name and ath10k does not fallback to the older naming scheme.

2017-02-21net: mvpp2: enable building on 64-bit platformsThomas Petazzoni
The mvpp2 is going to be extended to support the Marvell Armada 7K/8K platform, which is ARM64. As a preparation to this work, this commit enables building the mvpp2 driver on ARM64, by: - Adjusting the Kconfig dependency - Fixing the types used in the driver so that they are 32/64-bits compliant. We use dma_addr_t for DMA addresses, and unsigned long for virtual addresses. It is worth mentioning that after this commit, the driver is for now still only used on 32-bits platforms, and will only work on 32-bits platforms.

2017-02-21net: mvpp2: switch to build_skb() in the RX pathThomas Petazzoni
This commit adapts the mvpp2 RX path to use the build_skb() method. Not only build_skb() is now the recommended mechanism, but it also simplifies the addition of support for the PPv2.2 variant. Indeed, without build_skb(), we have to keep track for each RX descriptor of the physical address of the packet buffer, and the virtual address of the SKB. However, in PPv2.2 running on 64 bits platform, there is not enough space in the descriptor to store the virtual address of the SKB. So having to take care only of the address of the packet buffer, and building the SKB upon reception helps in supporting PPv2.2. The implementation is fairly straightforward: - mvpp2_skb_alloc() is renamed to mvpp2_buf_alloc() and no longer allocates a SKB. Instead, it allocates a buffer using the new mvpp2_frag_alloc() function, with enough space for the data and SKB. - The initialization of the RX buffers in mvpp2_bm_bufs_add() as well as the refill of the RX buffers in mvpp2_rx_refill() is adjusted accordingly. - Finally, the mvpp2_rx() is modified to use build_skb().

2017-02-21net: mvpp2: simplify MVPP2_PRS_RI_* definitionsThomas Petazzoni
Some of the MVPP2_PRS_RI_* definitions use the ~(value) syntax, which doesn't compile nicely on 64-bit. Moreover, those definitions are in fact unneeded, since they are always used in combination with a bit mask that ensures only the appropriate bits are modified. Therefore, such definitions should just be set to 0x0. In addition, as suggested by Russell King, we change the _MASK definitions to also use the BIT() macro so that it is clear they are related to the values defined afterwards. For example: #define MVPP2_PRS_RI_L2_CAST_MASK 0x600 #define MVPP2_PRS_RI_L2_UCAST ~(BIT(9) | BIT(10)) #define MVPP2_PRS_RI_L2_MCAST BIT(9) #define MVPP2_PRS_RI_L2_BCAST BIT(10) becomes #define MVPP2_PRS_RI_L2_CAST_MASK (BIT(9) | BIT(10)) #define MVPP2_PRS_RI_L2_UCAST 0x0 #define MVPP2_PRS_RI_L2_MCAST BIT(9) #define MVPP2_PRS_RI_L2_BCAST BIT(10) Because the values (MVPP2_PRS_RI_L2_UCAST, MVPP2_PRS_RI_L2_MCAST and MVPP2_PRS_RI_L2_BCAST) are always applied with MVPP2_PRS_RI_L2_CAST_MASK, and therefore there is no need for MVPP2_PRS_RI_L2_UCAST to be defined as ~(BIT(9) | BIT(10)). It fixes the following warnings when building the driver on a 64-bit platform (which is not possible as of this commit, but will be enabled in a follow-up commit): drivers/net/ethernet/marvell/mvpp2.c: In function ‘mvpp2_prs_mac_promisc_set’: drivers/net/ethernet/marvell/mvpp2.c:524:33: warning: large integer implicitly truncated to unsigned type [-Woverflow] #define MVPP2_PRS_RI_L2_UCAST ~(BIT(9) | BIT(10)) ^ drivers/net/ethernet/marvell/mvpp2.c:1459:33: note: in expansion of macro ‘MVPP2_PRS_RI_L2_UCAST’ mvpp2_prs_sram_ri_update(&pe, MVPP2_PRS_RI_L2_UCAST, Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com> Acked-by: Russell King <rmk+kernel@armlinux.org.uk> Signed-off-by: David S.

But they are only used in one place: if (is_recycle && (atomic_read(&bm_pool->in_use) < bm_pool->in_use_thresh)) return 0; However 'is_recycle', passed as argument to mvpp2_rx_refill() is always false.

The mvpp2_txq_bufs_free() function is called upon TX completion to DMA unmap TX buffers, and free the corresponding SKBs. It gets the references to the SKB to free and the DMA buffer to unmap from a per-CPU txq_pcpu data structure. However, the code currently increments the pointer to the next entry before doing the DMA unmap and freeing the SKB. It does not cause any visible problem because for a given SKB the TX completion is guaranteed to take place on the CPU where the TX was started. However, it is much more logical to increment the pointer to the next entry once the current entry has been completely unmapped/released.

When configuring the MVPP2_ISR_RX_THRESHOLD_REG with the RX coalescing time threshold, we do not check for the maximum allowed value supported by the driver, which means we might overflow and use a bogus value. This commit adds a check for this situation, and if a value higher than what is supported by the hardware is provided, then we use the maximum value supported by the hardware. In order to achieve this in a way that avoids overflow and rounding errors, we introduce two utility functions mvpp2_usec_to_cycles() and cycles_to_usec().

It makes a lot more sense to simply check if the value is too high, and if it's too high, limit it to the maximum possible value.

As noticed by Russell King, the last argument of mvpp2_rx_{pkts,time}_coal_set() is useless, since the packet/time coalescing value is already stored in the 'struct mvpp2_rx_queue *' passed as argument to these functions. So passing the packet/time value as an additional argument, and setting them again in the mvpp2_rx_queue structure is useles. This commit therefore gets rid of this additional argument, assuming the caller has assigned the appropriate value to rxq->pkts_coal or rxq->time_coal before calling the respective functions.

2017-02-21net: mvpp2: fix DMA address calculation in mvpp2_txq_inc_put()Thomas Petazzoni
When TX descriptors are filled in, the buffer DMA address is split between the tx_desc->buf_phys_addr field (high-order bits) and tx_desc->packet_offset field (5 low-order bits). However, when we re-calculate the DMA address from the TX descriptor in mvpp2_txq_inc_put(), we do not take tx_desc->packet_offset into account. This means that when the DMA address is not aligned on a 32 bytes boundary, we end up calling dma_unmap_single() with a DMA address that was not the one returned by dma_map_single(). This inconsistency is detected by the kernel when DMA_API_DEBUG is enabled. We fix this problem by properly calculating the DMA address in mvpp2_txq_inc_put().

Incremental patches can make the non-supported one available in the future if needed. Signed-off-by: Roopa Prabhu <roopa@cumulusnetworks.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2017-02-20virito-net: set queues after reset during xdp_setJason Wang
We set queues before reset which will cause a crash[1]. This is because is_xdp_raw_buffer_queue() depends on the old xdp queue pairs number to do the correct detection. So fix this by - passing xdp queue pairs and current queue pairs to virtnet_reset() - change vi->xdp_qp after reset but before refill, to make sure both free_unused_bufs() and refill can make correct detection of XDP. - remove the duplicated queue pairs setting before virtnet_reset() since we will do it inside virtnet_reset() [1] [ 74.328168] general protection fault: 0000 [#1] SMP [ 74.328625] Modules linked in: nfsd xfs libcrc32c virtio_net virtio_pci [ 74.329117] CPU: 0 PID: 2849 Comm: xdp2 Not tainted 4.10.0-rc7+ #499 [ 74.329577] Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS rel-1.10.1-0-g8891697-prebuilt.qemu-project.org 04/01/2014 [ 74.330424] task: ffff88007a894000 task.stack: ffffc90004388000 [ 74.330844] RIP: 0010:skb_release_head_state+0x28/0x80 [ 74.331298] RSP: 0018:ffffc9000438b8d0 EFLAGS: 00010206 [ 74.331676] RAX: 0000000000000000 RBX: ffff88007ad96300 RCX: 0000000000000000 [ 74.332217] RDX: ffff88007fc137a8 RSI: ffff88007fc0db28 RDI: 0001bf00000001be [ 74.332758] RBP: ffffc9000438b8d8 R08: 000000000005008f R09: 00000000000005f9 [ 74.333274] R10: ffff88007d001700 R11: ffffffff820a8a4d R12: ffff88007ad96300 [ 74.333787] R13: 0000000000000002 R14: ffff880036604000 R15: 000077ff80000000 [ 74.334308] FS: 00007fc70d8a7b40(0000) GS:ffff88007fc00000(0000) knlGS:0000000000000000 [ 74.334891] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 [ 74.335314] CR2: 00007fff4144a710 CR3: 000000007ab56000 CR4: 00000000003406f0 [ 74.335830] DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 [ 74.336373] DR3: 0000000000000000 DR6: 00000000fffe0ff0 DR7: 0000000000000400 [ 74.336895] Call Trace: [ 74.337086] skb_release_all+0xd/0x30 [ 74.337356] consume_skb+0x2c/0x90 [ 74.337607] free_unused_bufs+0x1ff/0x270 [virtio_net] [ 74.337988] ? vp_synchronize_vectors+0x3b/0x60 [virtio_pci] [ 74.338398] virtnet_xdp+0x21e/0x440 [virtio_net] [ 74.338741] dev_change_xdp_fd+0x101/0x140 [ 74.339048] do_setlink+0xcf4/0xd20 [ 74.339304] ? symcmp+0xf/0x20 [ 74.339529] ? mls_level_isvalid+0x52/0x60 [ 74.339828] ? mls_range_isvalid+0x43/0x50 [ 74.340135] ? nla_parse+0xa0/0x100 [ 74.340400] rtnl_setlink+0xd4/0x120 [ 74.340664] ? cpumask_next_and+0x30/0x50 [ 74.340966] rtnetlink_rcv_msg+0x7f/0x1f0 [ 74.341259] ? sock_has_perm+0x59/0x60 [ 74.341586] ? napi_consume_skb+0xe2/0x100 [ 74.342010] ? rtnl_newlink+0x890/0x890 [ 74.342435] netlink_rcv_skb+0x92/0xb0 [ 74.342846] rtnetlink_rcv+0x23/0x30 [ 74.343277] netlink_unicast+0x162/0x210 [ 74.343677] netlink_sendmsg+0x2db/0x390 [ 74.343968] sock_sendmsg+0x33/0x40 [ 74.344233] SYSC_sendto+0xee/0x160 [ 74.344482] ?

In the bnxt_init_one() failure path, bar1 and bar2 are not being unmapped. This commit fixes this issue. Reorganize the code so that bnxt_init_one()'s failure path and bnxt_remove_one() can call the same function to do the PCI cleanup.

If bnxt_hwrm_ring_free() is called during a failure path in bnxt_open(), it is possible that the completion rings have not been allocated yet. In that case, the completion doorbell has not been initialized, and calling bnxt_disable_int() will crash. Fix it by checking that the completion ring has been initialized before writing to the completion ring doorbell. Signed-off-by: Michael Chan <michael.chan@broadcom.com> Signed-off-by: David S.

git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm Pull power management updates from Rafael Wysocki: "The majority of changes go into the Operating Performance Points (OPP) framework and cpufreq this time, followed by devfreq and some scattered updates all over. The OPP changes are mostly related to switching over from RCU-based synchronization, that turned out to be overly complicated and problematic, to reference counting using krefs. In the cpufreq land there are core cleanups, documentation updates, a new driver for Broadcom BMIPS SoCs, a new cpufreq-dt sub-driver for TI SoCs that require special handling, ARM64 SoCs support for the qoriq driver, intel_pstate updates, powernv driver update and assorted fixes. The devfreq changes are mostly fixes related to the sysfs interface and some Exynos drivers updates. Apart from that, the cpuidle menu governor will support per-CPU PM QoS constraints for the wakeup latency now, some bugs in the wakeup IRQs framework are fixed, the generic power domains framework should handle asynchronous invocations of *noirq suspend/resume callbacks from now on, the analyze_suspend.py script is updated and there is a new tool for intel_pstate diagnostics.
