The driver imposes an arbitrary one second timeout on virtio requests, but the specification doesn't prevent the virtio device from taking longer to process requests, so remove this timeout to support all systems and device implementations.

When replugging the device the following message shows up: gpio gpiochip2: (dln2): detected irqchip that is shared with multiple gpiochips: please fix the driver. This also has the effect that interrupts won't work. The same problem would also show up if multiple devices where plugged in. Fix this by allocating the irq_chip data structure per instance like other drivers do. I don't know when this problem appeared, but it is present in 5.10.

Commit aeb58c86 ("thermal/drivers/int340x: processor_thermal: Suppot 64 bit RFIM responses") started using 'readq()' to read 64-bit status responses from the int340x hardware. That's all fine and good, but on 32-bit targets a 64-bit 'readq()' is ambiguous, since it's no longer an atomic access. Some hardware might require 64-bit accesses, and other hardware might want low word first or high word first. It's quite likely that the driver isn't relevant in a 32-bit environment any more, and there's a patch floating around to just make it depend on X86_64, but let's make it buildable on x86-32 anyway. The driver previously just read the low 32 bits, so the hardware certainly is ok with 32-bit reads, and in a little-endian environment the low word first model is the natural one. So just add the include for the 'io-64-nonatomic-lo-hi.h' version. Fixes: aeb58c86 ("thermal/drivers/int340x: processor_thermal: Suppot 64 bit RFIM responses") Reported-by:

Since 04128418 ("of/irq: Allow matching of an interrupt-map local to an interrupt controller"), the irq code favors using an interrupt-map over a interrupt-controller property if both are available, while the earlier behaviour was to ignore the interrupt-map altogether. However, we now end-up with the opposite behaviour, which is to ignore the interrupt-controller property even if the interrupt-map fails to match its input. This new behaviour breaks the AmigaOne X1000 machine, which ships with an extremely "creative" (read: broken) device tree. Fix this by allowing the interrupt-controller property to be selected when interrupt-map fails to match anything.

When using "devm_request_threaded_irq(,,,,IRQF_ONESHOT,,)" in a driver, only the first interrupt is handled, and following interrupts are never delivered (initially reported in [1]). That's because the RISC-V PLIC cannot EOI masked interrupts, as explained in the description of Interrupt Completion in the PLIC spec [2]: <quote> The PLIC signals it has completed executing an interrupt handler by writing the interrupt ID it received from the claim to the claim/complete register. The PLIC does not check whether the completion ID is the same as the last claim ID for that target. If the completion ID does not match an interrupt source that *is currently enabled* for the target, the completion is silently ignored. </quote> Re-enable the interrupt before completion if it has been masked during the handling, and remask it afterwards.

Commit 25b892b5 ("ARM: dts: arm: Update register-bit-led nodes 'reg' and node names") added a 'reg' property to nodes. This change has the side effect of changing how the kernel generates the device name. The assumption was a translatable 'reg' address is unique. However, in the case of the register-bit-led binding (and a few others) that is not the case. The 'mask' property must also be used in this case to make a unique device name.

ACS-3 introduced the ATA Identify Device Data log as mandatory. A warning message currently signals to the user if a device does not report supporting this log page in the log directory page, regardless of the ATA version of the device. Furthermore, this warning will appear for all attempts at accessing this missing log page during device revalidation. Since it is useless to constantly access the log directory and warn about this lack of support once we have discovered that the device does not support this log page, introduce the horkage flag ATA_HORKAGE_NO_ID_DEV_LOG to mark a device as lacking support for the Identify Device Data log page. Set this flag when ata_log_supported() returns false in ata_identify_page_supported(). The warning is printed only if the device ATA level is 10 or above (ACS-3 or above), and only once on device scan. With this flag set, the log directory page is not accessed again to test for Identify Device Data log page support. Signed-off-by:

This reverts commit 2a4d9408. Robert reported a NULL pointer dereference caused by the PCI core (local_pci_probe()) calling the i2c_designware_pci driver's .runtime_resume() method before the .probe() method. i2c_dw_pci_resume() depends on initialization done by i2c_dw_pci_probe(). Prior to 2a4d9408 ("PCI: Use to_pci_driver() instead of pci_dev->driver"), pci_pm_runtime_resume() avoided calling the .runtime_resume() method because pci_dev->driver had not been set yet. 2a4d9408 and b5f9c644 ("PCI: Remove struct pci_dev->driver"), removed pci_dev->driver, replacing it by device->driver, which *has* been set by this time, so pci_pm_runtime_resume() called the .runtime_resume() method when it previously had not.

MIGRATE_PFN_LOCKED is used to indicate to migrate_vma_prepare() that a source page was already locked during migrate_vma_collect(). If it wasn't then the a second attempt is made to lock the page. However if the first attempt failed it's unlikely a second attempt will succeed, and the retry adds complexity. So clean this up by removing the retry and MIGRATE_PFN_LOCKED flag. Destination pages are also meant to have the MIGRATE_PFN_LOCKED flag set, but nothing actually checks that. Link: https://lkml.kernel.org/r/20211025041608.289017-1-apopple@nvidia.com Signed-off-by:

The recent rework of PCI/MSI[X] masking moved the non-mask checks from the low level accessors into the higher level mask/unmask functions. This missed the fact that these accessors can be invoked from other places as well. The missing checks break XEN-PV which sets pci_msi_ignore_mask and also violates the virtual MSIX and the msi_attrib.maskbit protections. Instead of sprinkling checks all over the place, lift them back into the low level accessor functions. To avoid checking three different conditions combine them into one property of msi_desc::msi_attrib.

Some ATA drives are very slow to respond to READ_LOG_EXT and READ_LOG_DMA_EXT commands issued from ata_dev_configure() when the device is revalidated right after resuming a system or inserting the ATA adapter driver (e.g. ahci). The default 5s timeout (ATA_EH_CMD_DFL_TIMEOUT) used for these commands is too short, causing errors during the device configuration. Ex: ... ata9: SATA max UDMA/133 abar m524288@0x9d200000 port 0x9d200400 irq 209 ata9: SATA link up 6.0 Gbps (SStatus 133 SControl 300) ata9.00: ATA-9: XXX XXXXXXXXXXXXXXX, XXXXXXXX, max UDMA/133 ata9.00: qc timeout (cmd 0x2f) ata9.00: Read log page 0x00 failed, Emask 0x4 ata9.00: Read log page 0x00 failed, Emask 0x40 ata9.00: NCQ Send/Recv Log not supported ata9.00: Read log page 0x08 failed, Emask 0x40 ata9.00: 27344764928 sectors, multi 16: LBA48 NCQ (depth 32), AA ata9.00: Read log page 0x00 failed, Emask 0x40 ata9.00: ATA Identify Device Log not supported ata9.00: failed to set xfermode (err_mask=0x40) ata9: SATA link up 6.0 Gbps (SStatus 133 SControl 300) ata9.00: configured for UDMA/133 ... The timeout error causes a soft reset of the drive link, followed in most cases by a successful revalidation as that give enough time to the drive to become fully ready to quickly process the read log commands. However, in some cases, this also fails resulting in the device being dropped. Fix this by using adding the ata_eh_revalidate_timeouts entries for the READ_LOG_EXT and READ_LOG_DMA_EXT commands. This defines a timeout increased to 15s, retriable one time. Reported-by:

Commit bfe301eb ("net: mvpp2: convert to use mac_prepare()/mac_finish()") introduced a bug wherein it leaves the MAC RESET register asserted after mac_finish(), due to wrong order of function calls. Before it was: .mac_config() mvpp22_mode_reconfigure() assert reset mvpp2_xlg_config() deassert reset Now it is: .mac_prepare() .mac_config() mvpp2_xlg_config() deassert reset .mac_finish() mvpp2_xlg_config() assert reset Obviously this is wrong. This bug is triggered when phylink tries to change the PHY interface mode from a GMAC mode (sgmii, 1000base-x, 2500base-x) to XLG mode (10gbase-r, xaui). The XLG mode does not work since reset is left asserted. Only after ifconfig down && ifconfig up is called will the XLG mode work. Move the call to mvpp22_mode_reconfigure() to .mac_prepare() implementation. Since some of the subsequent functions need to know whether the interface is being changed, we unfortunately also need to pass around the new interface mode before setting port->phy_interface.

The initial virtio-mem spec states that while unplugged memory should not be read, the device still has to allow for reading unplugged memory inside the usable region. The primary motivation for this default handling was to simplify bringup of virtio-mem, because there were corner cases where Linux might have accidentially read unplugged memory inside added Linux memory blocks. In the meantime, we: 1. Removed /dev/kmem in commit bbcd53c9 ("drivers/char: remove /dev/kmem for good") 2. Disallowed access to virtio-mem device memory via /dev/mem in commit 2128f4e2 ("virtio-mem: disallow mapping virtio-mem memory via /dev/mem") 3. Sanitized access to virtio-mem device memory via /proc/kcore in commit 0daa322b ("fs/proc/kcore: don't read offline sections, logically offline pages and hwpoisoned pages") 4. Sanitized access to virtio-mem device memory via /proc/vmcore in commit ce281462 ("virtio-mem: kdump mode to sanitize /proc/vmcore access") "Accidential" access to unplugged memory is no longer possible; we can support the new VIRTIO_MEM_F_UNPLUGGED_INACCESSIBLE feature that will be required by some hypervisors implementing virtio-mem in the near future.
