2019-04-12iommu/amd: Set exclusion range correctlyJoerg Roedel
The exlcusion range limit register needs to contain the base-address of the last page that is part of the range, as bits 0-11 of this register are treated as 0xfff by the hardware for comparisons. So correctly set the exclusion range in the hardware to the last page which is _in_ the range.

2019-04-12PM / core: Propagate dev->power.wakeup_path when no callbacksUlf Hansson
The dev->power.direct_complete flag may become set in device_prepare() in case the device don't have any PM callbacks (dev->power.no_pm_callbacks is set). This leads to a broken behaviour, when there is child having wakeup enabled and relies on its parent to be used in the wakeup path. More precisely, when the direct complete path becomes selected for the child in __device_suspend(), the propagation of the dev->power.wakeup_path becomes skipped as well. Let's address this problem, by checking if the device is a part the wakeup path or has wakeup enabled, then prevent the direct complete path from being used.

2019-04-12drivers: firmware: psci: Announce support for OS initiated suspend modeUlf Hansson
PSCI firmware v1.0+, supports two different modes for CPU_SUSPEND. The Platform Coordinated mode, which is the default and mandatory mode, while support for the OS initiated (OSI) mode is optional. In some cases it's interesting for the user/developer to know if the OSI mode is supported by the PSCI FW, so print a message to the log if that is the case.

2019-04-12ACPI: button: reinitialize button state upon resumeZhang Rui
With commit dfa46c50f65b ("ACPI / button: Fix an issue in button.lid_init_state=ignore mode"), the lid device is considered to be not compliant to SW_LID if the Lid state is unchanged when updating it. This is not wrong, but we overlooked the resume case, where Lid state is updated unconditionally in the button driver .resume() callback. And this results in warning message "ACPI: button: The lid device is not compliant to SW_LID." after resume, if the machine is suspended with Lid opened and then resumed with Lid opened. Fix this by flushing the cached lid state before updating the Lid device in .resume() callback.

2019-04-11PM / Domains: Add genpd governor for CPUsUlf Hansson
After some preceding changes, PM domains managed by genpd may contain CPU devices, so idle state residency values should be taken into account during the state selection process. [The residency value is the minimum amount of time to be spent by a CPU (or a group of CPUs) in an idle state in order to save more energy than could be saved by picking up a shallower idle state.] For this purpose, add a new genpd governor, pm_domain_cpu_gov, to be used for selecting idle states of PM domains with CPU devices attached either directly or through subdomains. The new governor computes the minimum expected idle duration for all online CPUs attached to a PM domain and its subdomains. Next, it finds the deepest idle state whose target residency is within the expected idle duration and selects it as the target idle state of the domain. It should be noted that the minimum expected idle duration computation is based on the closest timer event information stored in the per-CPU variables cpuidle_devices for all of the CPUs in the domain. That needs to be revisited in future, as obviously there are other reasons why a CPU may be woken up from idle.

2019-04-11nvmet: fix discover log page when offsets are usedKeith Busch
The nvme target hadn't been taking the Get Log Page offset parameter into consideration, and so has been returning corrupted log pages when offsets are used. Since many tools, including nvme-cli, split the log request to 4k, we've been breaking discovery log responses when more than 3 subsystems exist. Fix the returned data by internally generating the entire discovery log page and copying only the requested bytes into the user buffer. The command log page offset type has been modified to a native __le64 to make it easier to extract the value from a command.

2019-04-11nvme-fc: correct csn initialization and increments on errorJames Smart
This patch fixes a long-standing bug that initialized the FC-NVME cmnd iu CSN value to 1. Early FC-NVME specs had the connection starting with CSN=1. By the time the spec reached approval, the language had changed to state a connection should start with CSN=0. This patch corrects the initialization value for FC-NVME connections. Additionally, in reviewing the transport, the CSN value is assigned to the new IU early in the start routine. It's possible that a later dma map request may fail, causing the command to never be sent to the controller. Change the location of the assignment so that it is immediately prior to calling the lldd. Add a comment block to explain the impacts if the lldd were to additionally fail sending the command.

When fb is tiled and fb->height isn't the multiple of tile's height, the format fb->size = fb->stride * fb->height, will get a smaller size than the actual size. As the memory height of tiled fb should be multiple of tile's height.

After adding a team interface to bridge, the team interface will enter promisc mode. Then if we add a new slave to team0, the slave will keep promisc off.

2019-04-10clk: x86: Add system specific quirk to mark clocks as criticalDavid Müller
Since commit 648e921888ad ("clk: x86: Stop marking clocks as CLK_IS_CRITICAL"), the pmc_plt_clocks of the Bay Trail SoC are unconditionally gated off. Unfortunately this will break systems where these clocks are used for external purposes beyond the kernel's knowledge. Fix it by implementing a system specific quirk to mark the necessary pmc_plt_clks as critical.

2019-04-10PCI: pciehp: Ignore Link State Changes after powering off a slotSergey Miroshnichenko
During a safe hot remove, the OS powers off the slot, which may cause a Data Link Layer State Changed event. The slot has already been set to OFF_STATE, so that event results in re-enabling the device, making it impossible to safely remove it. Clear out the Presence Detect Changed and Data Link Layer State Changed events when the disabled slot has settled down. It is still possible to re-enable the device if it remains in the slot after pressing the Attention Button by pressing it again. Fixes the problem that Micah reported below: an NVMe drive power button may not actually turn off the drive.

2019-04-10ibmvnic: Fix netdev feature clobbering during a resetThomas Falcon
While determining offload capabilities of backing hardware during a device reset, the driver is clobbering current feature settings. Update hw_features on reset instead of features unless a feature is enabled that is no longer supported on the current backing device. Also enable features that were not supported prior to the reset but were previously enabled or requested by the user. This can occur if the reset is the result of a carrier change, such as a device failover or partition migration. Signed-off-by: Thomas Falcon <tlfalcon@linux.ibm.com> Signed-off-by: David S.

2019-04-10mlxsw: spectrum_buffers: Add a multicast pool for Spectrum-2Ido Schimmel
In Spectrum-1, when a multicast packet is admitted to the shared buffer it increases the quotas of all the ports and {port, TC} to which it is forwarded to. The above means that multicast packets are accounted multiple times in the shared buffer and can therefore cause the associated shared buffer pool to fill up very quickly. To work around this issue, commit e83c045e53d7 ("mlxsw: spectrum_buffers: Configure MC pool") added a dedicated multicast pool in which multicast packets are accounted. The issue is not present in Spectrum-2, but in order to be backward compatible with Spectrum-1, its default behavior is to allow a multicast packet to increase multiple egress quotas instead of one. Until the new (non-backward compatible) mode is supported, configure a dedicated multicast pool as in Spectrum-1.

2019-04-10mlxsw: spectrum_router: Do not check VRF MAC addressIdo Schimmel
Commit 74bc99397438 ("mlxsw: spectrum_router: Veto unsupported RIF MAC addresses") enabled the driver to veto router interface (RIF) MAC addresses that it cannot support. This check should only be performed for interfaces for which the driver actually configures a RIF. A VRF upper is not one of them, so ignore it. Without this patch it is not possible to set an IP address on the VRF device and use it as a loopback.
