2019-07-04ACPI: PM: Unexport acpi_device_get_power()Rafael J. Wysocki
Using acpi_device_get_power() outside of ACPI device initialization and ACPI sysfs is problematic due to the way in which power resources are handled by it, so unexport it and add a paragraph explaining the pitfalls to its kerneldoc comment.

2019-07-04iommu/arm-smmu-v3: Invalidate ATC when detaching a deviceJean-Philippe Brucker
We make the invalid assumption in arm_smmu_detach_dev() that the ATC is clear after calling pci_disable_ats(). For one thing, only enabling the PCIe ATS capability constitutes an implicit invalidation event, so the comment was wrong. More importantly, the ATS capability isn't necessarily disabled by pci_disable_ats() in a PF, if the associated VFs have ATS enabled. Explicitly invalidate all ATC entries in arm_smmu_detach_dev(). The endpoint cannot form new ATC entries because STE.EATS is clear.

2019-07-04gpio: stp-xway: improve module clock error handlingMartin Blumenstingl
Three module clock error handling improvements: - use devm_clk_get() so the clock instance can be freed if devm_gpiochip_add_data() fails later on - switch to clk_prepare_enable() so the driver is ready whenever the lantiq target switches to the common clock framework - disable the clock again (using clk_disable_unprepare()) if devm_gpiochip_add_data() All of these are virtually no-ops with the current lantiq target. However, these will be relevant if we switch to the common clock framework.

Return early if devm_gpiochip_add_data() returns an error instead of having two consecutive "if (!ret) ..." statements. Also make xway_stp_hw_init() return void because it unconditionally returns 0. While here also update the kerneldoc comment for xway_stp_hw_init(). These changes makes the error handling within the driver consistent. No functional changes intended.

Fix it by: - Moving the second descriptor after the buffer, as moving the buffer after the descriptor would make it more complex for other cipher operations (AEAD, ABLKCIPHER) - Skip the bytes taken from the new request to complete the previous one by moving the SG list forward.

2019-07-03clocksource/drivers: Make Hyper-V clocksource ISA agnosticMichael Kelley
Hyper-V clock/timer code and data structures are currently mixed in with other code in the ISA independent drivers/hv directory as well as the ISA dependent Hyper-V code under arch/x86. Consolidate this code and data structures into a Hyper-V clocksource driver to better follow the Linux model. In doing so, separate out the ISA dependent portions so the new clocksource driver works for x86 and for the in-process Hyper-V on ARM64 code. To start, move the existing clockevents code to create the new clocksource driver. Update the VMbus driver to call initialization and cleanup routines since the Hyper-V synthetic timers are not independently enumerated in ACPI. No behavior is changed and no new functionality is added.

2019-07-03gpio: siox: Pass irqchip when adding gpiochipLinus Walleij
We need to convert all old gpio irqchips to pass the irqchip setup along when adding the gpio_chip. For chained irqchips this is a pretty straight-forward conversion.

2019-07-03ACPI: PM: Introduce "poweroff" callbacks for ACPI PM domain and LPSSRafael J. Wysocki
In general, it is not correct to call pm_generic_suspend(), pm_generic_suspend_late() and pm_generic_suspend_noirq() during the hibernation's "poweroff" transition, because device drivers may provide special callbacks to be invoked then and the wrappers in question cause system suspend callbacks to be run. Unfortunately, that happens in the ACPI PM domain and ACPI LPSS. To address this potential issue, introduce "poweroff" callbacks for the ACPI PM and LPSS that will use pm_generic_poweroff(), pm_generic_poweroff_late() and pm_generic_poweroff_noirq() as appropriate.

2019-07-03ACPI: PM: Simplify and fix PM domain hibernation callbacksRafael J. Wysocki
First, after a previous change causing all runtime-suspended devices in the ACPI PM domain (and ACPI LPSS devices) to be resumed before creating a snapshot image of memory during hibernation, it is not necessary to worry about the case in which them might be left in runtime-suspend any more, so get rid of the code related to that from ACPI PM domain and ACPI LPSS hibernation callbacks. Second, it is not correct to use pm_generic_resume_early() and acpi_subsys_resume_noirq() in hibernation "restore" callbacks (which currently happens in the ACPI PM domain and ACPI LPSS), so introduce proper _restore_late and _restore_noirq callbacks for the ACPI PM domain and ACPI LPSS.

2019-07-03PM: ACPI/PCI: Resume all devices during hibernationRafael J. Wysocki
Both the PCI bus type and the ACPI PM domain avoid resuming runtime-suspended devices with DPM_FLAG_SMART_SUSPEND set during hibernation (before creating the snapshot image of system memory), but that turns out to be a mistake. It leads to functional issues and adds complexity that's hard to justify. For this reason, resume all runtime-suspended PCI devices and all devices in the ACPI PM domains before creating a snapshot image of system memory during hibernation.

2019-07-02scsi: target/iblock: Fix overrun in WRITE SAME emulationRoman Bolshakov
WRITE SAME corrupts data on the block device behind iblock if the command is emulated. The emulation code issues (M - 1) * N times more bios than requested, where M is the number of 512 blocks per real block size and N is the NUMBER OF LOGICAL BLOCKS specified in WRITE SAME command. So, for a device with 4k blocks, 7 * N more LBAs gets written after the requested range. The issue happens because the number of 512 byte sectors to be written is decreased one by one while the real bios are typically from 1 to 8 512 byte sectors per bio.
