commit 7a6cb0ab upstream. Avoid entering "RTC-only mode" at poweroff. It is unsupported by most versions of BeagleBone, and risks hardware damage. The damaging configuration is having system-power-controller without ti,pmic-shutdown-controller. Reported-by:

commit e96998fc upstream. According to the Armada 38x datasheet, the window base address registers value is set in bits [31:4] of the register and corresponds to the transaction address bits [47:20]. Therefore, the 32bit base address value should be shifted right by 20bits and left by 4bits, resulting in 16 bit shift right. The bug as not been noticed yet because if the memory available on the platform is less than 2GB, then the base address is zero.

commit 4ed6a540 upstream. When we use 'intel_iommu=igfx_off' to disable translation for the graphics, and when we discover that the BIOS has misconfigured the DMAR setup for I/OAT, we use a special DUMMY_DEVICE_DOMAIN_INFO value in dev->archdata.iommu to indicate that translation is disabled. With passthrough mode, we were attempting to dereference that as a normal pointer to a struct device_domain_info when setting up an identity mapping for the affected device. This fixes the problem by making device_to_iommu() explicitly check for the special value and indicate that no IOMMU was found to handle the devices in question. Signed-off-by:

commit 18436afd upstream. Commit c875d2c1 ("iommu/vt-d: Exclude devices using RMRRs from IOMMU API domains") prevents certain options for devices with RMRRs. This even prevents those devices from getting a 1:1 mapping with 'iommu=pt', because we don't have the code to handle *preserving* the RMRR regions when moving the device between domains. There's already an exclusion for USB devices, because we know the only reason for RMRRs there is a misguided desire to keep legacy keyboard/mouse emulation running in some theoretical OS which doesn't have support for USB in its own right... but which *does* enable the IOMMU. Add an exclusion for graphics devices too, so that 'iommu=pt' works there. We should be able to successfully assign graphics devices to guests too, as long as the initial handling of stolen memory is reconfigured appropriately. This has certainly worked in the past.

commit 5f35b9cd upstream. Commit 334c86c4 ("MIPS: IRQ: Add stackoverflow detection") added kernel stack overflow detection, however it only enabled it conditional upon the preprocessor definition DEBUG_STACKOVERFLOW, which is never actually defined. The Kconfig option is called DEBUG_STACKOVERFLOW, which manifests to the preprocessor as CONFIG_DEBUG_STACKOVERFLOW, so switch it to using that definition instead.

commit 088df2cc upstream. On some v7 devices (e.g. Lenovo-E550) the deltas reported are typically only in the 0-1 range dividing this by 2 results in a range of 0-0. And even for v7 devices where this does not lead to making the trackstick entirely unusable, it makes it twice as slow as before we added v7 support and were using the ps/2 mouse emulation of the dual point setup. If some kind of generic slowdown is actually necessary for some devices, then that belongs in userspace, not in the kernel. Reported-and-tested-by:

commit ea114fc2 upstream. The driver worked around an error in the MAYA44 USB(+)'s mixer unit descriptor by aborting before parsing the missing field. However, aborting parsing too early prevented parsing of the other units connected to this unit, so the capture mixer controls would be missing. Fix this by moving the check for this descriptor error after the parsing of the unit's input pins. Reported-by:

commit 425be567 upstream. The early_idt_handlers asm code generates an array of entry points spaced nine bytes apart. It's not really clear from that code or from the places that reference it what's going on, and the code only works in the first place because GAS never generates two-byte JMP instructions when jumping to global labels. Clean up the code to generate the correct array stride (member size) explicitly. This should be considerably more robust against screw-ups, as GAS will warn if a .fill directive has a negative count. Using '. =' to advance would have been even more robust (it would generate an actual error if it tried to move backwards), but it would pad with nulls, confusing anyone who tries to disassemble the code. The new scheme should be much clearer to future readers. While we're at it, improve the comments and rename the array and common code. Binutils may start relaxing jumps to non-weak labels. If so, this change will fix our build, and we may need to backport this change.

This actually wasn't happening due to a short-circuit that only checked the DP_AUX_CH_CTL_DONE bit in status rather than checking that the operation was done and that DP_AUX_CH_CTL_TIME_OUT_ERROR was not set.

commit 392bceed upstream. The driver configures the IDLE condition to interrupt the SDMA engine. Since the SDMA UART ROM script doesn't clear the IDLE bit itself, this caused repeated 1-byte DMA transfers, regardless of available data in the RX FIFO. Also, when returning due to the IDLE condition, the UART ROM script already increased its counter, causing residue to be off by one. This patch clears the IDLE condition to avoid repeated 1-byte DMA transfers and decreases count by when the DMA transfer was aborted due to the IDLE condition, fixing serial transfers using DMA on i.MX6Q.

commit a00918d0 upstream. Regression in commit 638139eb ("usb: hub: allow to process more usb hub events in parallel") The regression resulted in intermittent failure to initialise a 10-port hub (with three internal VL812 4-port hub controllers) on boot, with a failure rate of around 8%, due to multiple race conditions when accessing addr_dev and slot_id in struct xhci_hcd. This regression also exposed a problem with xhci_setup_device, which "should be protected by the usb_address0_mutex" but no longer is due to commit 6fecd4f2 ("USB: separate usb_address0 mutexes for each bus") With separate buses (and locks) it is no longer the case that a single lock will protect xhci_setup_device from accesses by two parallel threads processing events on the two buses. Fix this by adding a mutex to protect addr_dev and slot_id in struct xhci_hcd, and by making the assignment of slot_id atomic. Fixes multiple boot errors: [ 0.583008] xhci_hcd 0000:00:14.0: Bad Slot ID 2 [ 0.583009] xhci_hcd 0000:00:14.0: Could not allocate xHCI USB device data structures [ 0.583012] usb usb1-port3: couldn't allocate usb_device And: [ 0.637409] xhci_hcd 0000:00:14.0: Error while assigning device slot ID [ 0.637417] xhci_hcd 0000:00:14.0: Max number of devices this xHCI host supports is 32.

commit 9df56035 upstream. There are a few issues with the burst mode support. For one we don't setup the rx buffer, so the buffer will never be filled and all samples will read as the zero. Furthermore the tx buffer has the wrong type, which means the driver sends the wrong command and not the right data is returned. The final issue is that in burst mode all channels are transferred. Hence the length of the transfer length should be the number of hardware channels * 2 bytes. Currently the driver uses indio_dev->scan_bytes for this. But if the timestamp channel is enabled the scan_bytes will be larger than the burst length. Fix this by just calculating the burst length based on the number of hardware channels. Signed-off-by:

commit c2a8b623 upstream. We unfortunately can't use ~0UL for the scan mask to indicate that the only valid scan mask is all channels selected. The IIO core needs the exact mask to work correctly and not a super-set of it. So calculate the masked based on the channels that are available for a particular device. Signed-off-by:

commit 7323d598 upstream. Previously, the two voltage channels had the same ID, which didn't cause conflicts in sysfs only because one channel is named and the other isn't; this is still violating the spec though, two indexed channels should never have the same index. Signed-off-by:

commit cc4a84c3 upstream. While adding support for 7425 PHY in the 7xxx PHY driver, the ID that was used was actually coming from an external PHY: a BCM5461x. Fix this by using the proper ID for the internal 7425 PHY and set the PHY_IS_INTERNAL flag, otherwise consumers of this PHY driver would not be able to properly identify it as such.
