commit 8807d356 upstream. GPIO lines for the CM36651 sensor I2C bus use the normal not the inverted polarity. This bug has been there since adding the CM36651 sensor by commit 85cb4e0b ("ARM: dts: add cm36651 light/proximity sensor node for exynos4412-trats2"), but went unnoticed because the "i2c-gpio" driver ignored the GPIO polarity specified in the device-tree. The recent conversion of "i2c-gpio" driver to the new, descriptor based GPIO API, automatically made it the DT-specified polarity aware, what broke the CM36651 sensor operation.

commit 35509737 upstream. The PL310 Auxiliary Control Register shouldn't have the "Full line of zero" optimization bit being set before L2 cache is enabled. The L2X0 driver takes care of enabling the optimization by itself. This patch fixes a noisy error message on Tegra20 and Tegra30 telling that cache optimization is erroneously enabled without enabling it for the CPU: L2C-310: enabling full line of zeros but not enabled in Cortex-A9 Cc: <stable@vger.kernel.org> Signed-off-by:

commit b5945214 upstream. cpu_pm_notify() is basically a wrapper of notifier_call_chain(). notifier_call_chain() doesn't initialize *nr_calls to 0 before it starts incrementing it--presumably it's up to the callers to do this. Unfortunately the callers of cpu_pm_notify() don't init *nr_calls. This potentially means you could get too many or two few calls to CPU_PM_ENTER_FAILED or CPU_CLUSTER_PM_ENTER_FAILED depending on the luck of the stack. Let's fix this.

commit 54505a1e upstream. The commits cd0e00c1 and 92d7223a broke boot on the Alpha Avanti platform. The patches move memory barriers after a write before the write. The result is that if there's iowrite followed by ioread, there is no barrier between them. The Alpha architecture allows reordering of the accesses to the I/O space, and the missing barrier between write and read causes hang with serial port and real time clock. This patch makes barriers confiorm to the specification. 1. We add mb() before readX_relaxed and writeX_relaxed - memory-barriers.txt claims that these functions must be ordered w.r.t. each other. Alpha doesn't order them, so we need an explicit barrier. 2. We add mb() before reads from the I/O space - so that if there's a write followed by a read, there should be a barrier between them.

commit f354157a upstream. Currently, for EINT_TYPE GPIOs, the CON and FLTCON registers are saved and restored over a suspend/resume cycle. However, the EINT_MASK registers are not. On S5PV210 at the very least, these registers are not retained over suspend, leading to the interrupts remaining masked upon resume and therefore no interrupts being triggered for the device. There should be no effect on any SoCs that do retain these registers as theoretically we would just be re-writing what was already there.

commit 165ae7a8 upstream. igb device gets runtime suspended when there's no link partner. We can't get correct speed under that state: $ cat /sys/class/net/enp3s0/speed 1000 In addition to that, an error can also be spotted in dmesg: [ 385.991957] igb 0000:03:00.0 enp3s0: PCIe link lost Since device can only be runtime suspended when there's no link partner, we can skip reading register and let the following logic set speed and duplex with correct status. The more generic approach will be wrap get_link_ksettings() with begin() and complete() callbacks. However, for this particular issue, begin() calls igb_runtime_resume() , which tries to rtnl_lock() while the lock is already hold by upper ethtool layer. So let's take this approach until the igb_runtime_resume() no longer needs to hold rtnl_lock. CC: stable <stable@vger.kernel.org> Suggested-by:

commit bfcba38d upstream. v4l2_ctrl_handler_free() uses hdl->lock, which in ov5640 driver is set to sensor's own sensor->lock. In ov5640_remove(), the driver destroys the sensor->lock first, and then calls v4l2_ctrl_handler_free(), resulting in the use of the destroyed mutex. Fix this by calling moving the mutex_destroy() to the end of the cleanup sequence, as there's no need to destroy the mutex as early as possible. Signed-off-by:

commit 6a29d134 upstream. Since the driver was first introduced into the kernel, it has only handled the ciphers associated with WEP, WPA, and WPA2. It fails with WPA3 even though mac80211 can handle those additional ciphers in software, b43legacy did not report that it could handle them. By setting MFP_CAPABLE using ieee80211_set_hw(), the problem is fixed. With this change, b43legacy will handle the ciphers it knows in hardware, and let mac80211 handle the others in software. It is not necessary to use the module parameter NOHWCRYPT to turn hardware encryption off. Although this change essentially eliminates that module parameter, I am choosing to keep it for cases where the hardware is broken, and software encryption is required for all ciphers. Signed-off-by:

commit ec4d3e3a upstream. This patch fixes commit 75388acd ("add mac80211-based driver for legacy BCM43xx devices") In https://bugzilla.kernel.org/show_bug.cgi?id=207093, a defect in b43legacy is reported. Upon testing, thus problem exists on PPC and X86 platforms, is present in the oldest kernel tested (3.2), and has been present in the driver since it was first added to the kernel. The problem is a corrupted channel status received from the device. Both the internal card in a PowerBook G4 and the PCMCIA version (Broadcom BCM4306 with PCI ID 14e4:4320) have the problem. Only Rev, 2 (revision 4 of the 802.11 core) of the chip has been tested. No other devices using b43legacy are available for testing. Various sources of the problem were considered. Buffer overrun and other sources of corruption within the driver were rejected because the faulty channel status is always the same, not a random value. It was concluded that the faulty data is coming from the device, probably due to a firmware bug. As that source is not available, the driver must take appropriate action to recover. At present, the driver reports the error, and them continues to process the bad packet. This is believed that to be a mistake, and the correct action is to drop the correpted packet.

commit d601afca upstream. It's an error if the value of the RX/TX tail descriptor does not match what was written. The error condition is true regardless the duration of the interference from ME. But the driver only performs the reset if E1000_ICH_FWSM_PCIM2PCI_COUNT (2000) iterations of 50us delay have transpired. The extra condition can lead to inconsistency between the state of hardware as expected by the driver. Fix this by dropping the check for number of delay iterations. While at it, also make __ew32_prepare() static as it's not used anywhere else. CC: stable <stable@vger.kernel.org> Signed-off-by:

commit aa0ce96d upstream. Root Complex Integrated Endpoints (RCiEPs) do not have an upstream bridge, so pci_configure_mps() previously ignored them, which may result in reduced performance. Instead, program the Max_Payload_Size of RCiEPs to the maximum supported value (unless it is limited for the PCIE_BUS_PEER2PEER case). This also affects the subsequent programming of Max_Read_Request_Size because Linux programs MRRS based on the MPS value.

[ Upstream commit 6d3113a1 ] In btrfs_submit_direct_hook(), if a direct I/O write doesn't span a RAID stripe or chunk, we submit orig_bio without cloning it. In this case, we don't increment pending_bios. Then, if btrfs_submit_dio_bio() fails, we decrement pending_bios to -1, and we never complete orig_bio. Fix it by initializing pending_bios to 1 instead of incrementing later. Fixing this exposes another bug: we put orig_bio prematurely and then put it again from end_io. Fix it by not putting orig_bio. After this change, pending_bios is really more of a reference count, but I'll leave that cleanup separate to keep the fix small.

[ Upstream commit a17beb1a ] Although not allowed by the PCI specs, some multi-function devices have power dependencies between the functions. For example, function 1 may not work unless function 0 is in the D0 power state. The existing quirk_gpu_hda() adds a device link to express this dependency for GPU and HDA devices, but it really is not specific to those device types. Generalize it and rename it to pci_create_device_link() so we can create dependencies between any "consumer" and "producer" functions of a multi-function device, where the consumer is only functional if the producer is in D0. This reorganization should not affect any functionality. Link: https://lore.kernel.org/lkml/20190606092225.17960-2-abhsahu@nvidia.comSigned-off-by:

The root PCI address however remained at the same address as the model 30h.

I would have been happy about dropping my patch but unlike for his patch series, I had already Cc:ed the x86 people and they already reviewed the changes. Since Vicki has not answered to any email after his initial series, let's assume she is on vacation and let's avoid duplication of reviews from the maintainers and merge my series.

[ Upstream commit b516ea58 ] Many NVIDIA GPUs can be configured as either a single-function video device or a multi-function device with video at function 0 and an HDA audio controller at function 1. The HDA controller can be enabled or disabled by a bit in the function 0 config space. Some BIOSes leave the HDA disabled, which means the HDMI connector from the NVIDIA GPU may not work. Sometimes the BIOS enables the HDA if an HDMI cable is connected at boot time, but that doesn't handle hotplug cases. Enable the HDA controller on device enumeration and resume and re-read the header type, which tells us whether the GPU is a multi-function device. This quirk is limited to NVIDIA PCI devices with the VGA Controller device class. This is expected to correspond to product configurations where the NVIDIA GPU has connectors attached. Other products where the device class is 3D Controller are expected to correspond to configurations where the NVIDIA GPU is dedicated (dGPU) and has no connectors. See original post (URL below) for more details. This commit takes inspiration from an earlier patch by Daniel Drake.

[ Upstream commit 6d2e369f ] The NVIDIA Turing GPU is a multi-function PCI device with the following functions: - Function 0: VGA display controller - Function 1: Audio controller - Function 2: USB xHCI Host controller - Function 3: USB Type-C UCSI controller Function 0 is tightly coupled with other functions in the hardware. When function 0 is in D3, it gates power for hardware blocks used by other functions, which means those functions only work when function 0 is in D0. If any of these functions (1/2/3) are in D0, then function 0 should also be in D0. Commit 07f4f97d ("vga_switcheroo: Use device link for HDA controller") already creates a device link to show the dependency of function 1 on function 0 of this GPU. Create additional device links to express the dependencies of functions 2 and 3 on function 0. This means function 0 will be in D0 if any other function is in D0. [bhelgaas: I think the PCI spec expectation is that functions can be power-managed independently, so I don't think this device is technically compliant. For example, the PCIe r5.0 spec, sec 1.4, says "the PCI/PCIe hardware/software model includes architectural constructs necessary to discover, configure, and use a Function, without needing Function-specific knowledge" and sec 5.1 says "D states are associated with a particular Function" and "PM provides ... a mechanism to identify power management capabilities of a given Function [and] the ability to transition a Function into a certain power management state."] Link: https://lore.kernel.org/lkml/20190606092225.17960-3-abhsahu@nvidia.comSigned-off-by:
