2017-07-02acpi/nfit: Issue Start ARS to retrieve existing recordsToshi Kani
ACPI 6.2 defines in section 9.20.7.2 that the OSPM may call a Start ARS with Flags Bit [1] set upon receiving the 0x81 notification. Upon receiving the notification, the OSPM may decide to issue a Start ARS with Flags Bit [1] set to prepare for the retrieval of existing records and issue the Query ARS Status function to retrieve the records. Add support to call a Start ARS from acpi_nfit_uc_error_notify() with ND_ARS_RETURN_PREV_DATA set when HW_ERROR_SCRUB_ON is not set.

2017-07-02nvme: Quirks for PM1725 controllersMartin K. Petersen
PM1725 controllers have a couple of quirks that need to be handled in the driver: - I/O queue depth must be limited to 64 entries on controllers that do not report MQES. - The host interface registers go offline briefly while resetting the chip. Thus a delay is needed before checking whether the controller is ready. Note that the admin queue depth is also limited to 64 on older versions of this board. Since our NVME_AQ_DEPTH is now 32 that is no longer an issue. Signed-off-by: Martin K. Petersen <martin.petersen@oracle.com> Signed-off-by: Sagi Grimberg <sagi@grimberg.me>

This is inefficient in terms of memory usage (buffers are less than 1 page in size, so we lose due to alignment), and also time spent in doing 3 allocations + de-allocations per slot, instead of 1.

2017-07-01scsi: cxlflash: Update debug prints in reset handlersMatthew R. Ochs
The device and host reset handler contain debug prints to help identify the entities being reset. Today these reset handlers are based on a SCSI EH design that uses a SCSI command reference as a means of identifying the target entity. As such, the debug trace includes the SCSI command pointer and associated CDB. This is not necessary as the SCSI command is simply the messenger in these scenarios. Refactor the debug prints in the host and reset handlers to only present information that is applicable given the function scope. Signed-off-by: Matthew R.

2017-07-01scsi: Add STARGET_CREATED_REMOVE state to scsi_target_stateEwan D. Milne
The addition of the STARGET_REMOVE state had the side effect of introducing a race condition that can cause a crash. scsi_target_reap_ref_release() checks the starget->state to see if it still in STARGET_CREATED, and if so, skips calling transport_remove_device() and device_del(), because the starget->state is only set to STARGET_RUNNING after scsi_target_add() has called device_add() and transport_add_device(). However, if an rport loss occurs while a target is being scanned, it can happen that scsi_remove_target() will be called while the starget is still in the STARGET_CREATED state. In this case, the starget->state will be set to STARGET_REMOVE, and as a result, scsi_target_reap_ref_release() will take the wrong path. The end result is a panic: [ 1255.356653] Oops: 0000 [#1] SMP [ 1255.360154] Modules linked in: x86_pkg_temp_thermal kvm_intel kvm irqbypass crc32c_intel ghash_clmulni_i [ 1255.393234] CPU: 5 PID: 149 Comm: kworker/u96:4 Tainted: G W 4.11.0+ #8 [ 1255.401879] Hardware name: Dell Inc.

2017-07-01nfp: provide infrastructure for offloading flower based TC filtersPieter Jansen van Vuuren
Adds a flower based TC offload handler for representor devices, this is in addition to the bpf based offload handler. The changes in this patch will be used in a follow-up patch to add tc flower offload to the NFP. The flower app enables tc offloads on representors by default.

Add phys_switch_id support by allowing lookup of SWITCHDEV_ATTR_ID_PORT_PARENT_ID via the nfp_repr_port_attr_get switchdev operation. This is visible to user-space in the phys_switch_id attribute of a netdev. e.g. cd /sys/devices/pci0000:00/0000:00:01.0/0000:01:00.0 find . -name phys_switch_id | xargs grep . ./net/eth3/phys_switch_id:00154d1300bd ./net/eth4/phys_switch_id:00154d1300bd ./net/eth2/phys_switch_id:00154d1300bd grep: ./net/eth5/phys_switch_id: Operation not supported In the above eth2 and eth3 and representor netdevs for the first and second physical port. eth4 is the representor for the PF.

2017-06-30platform/x86: fujitsu-laptop: rework debuggingMichał Kępień
Using a dedicated Kconfig option for enabling debugging means the user may be forced to recompile their kernel in order to gather debugging information, which is inconvenient. Replace custom debugging infrastructure with standard logging functions, taking advantage of dynamic debug. Replace a pr_info() call inside an ACPI callback with an acpi_handle_info() call. The following mapping was used: - FUJLAPTOP_DBG_ERROR -> acpi_handle_err() - FUJLAPTOP_DBG_WARN -> acpi_handle_info() / dev_info() - FUJLAPTOP_DBG_INFO -> acpi_handle_debug() - FUJLAPTOP_DBG_TRACE -> acpi_handle_debug() / dev_dbg() This means that some events which used to only be logged when the user explicitly requested it will now be logged by default: - ACPI method evaluation errors, - unknown ACPI notification codes, - unknown hotkey scancodes. The first type of events should happen rarely, if ever at all. The rest is interesting from driver development perspective as their presence in the logs will mean the driver is unaware of certain events, handling of which should be implemented.

2017-06-30platform/x86: fujitsu-laptop: do not evaluate ACPI _INI methodsMichał Kępień
acpi_ns_initialize_devices(), which is called during system-wide ACPI initialization, already detects and calls all _INI methods belonging to objects present in ACPI tables. There is no need to call these methods again every time the module is loaded because they only initialize status flags and hotkey-related variables; status flags are effectively constants, hotkey-related variables may be assigned non-zero values before acpi_fujitsu_laptop_add() is called, but that does not really matter as we drain the scancodes queued in the firmware's ring buffer before doing anything else. Remove sections of code which invoke and check evaluation status of the _INI methods belonging to the ACPI devices handled by the driver.

2017-06-30platform/x86: fujitsu-laptop: do not update ACPI device power statusMichał Kępień
Calling acpi_bus_update_power() for ACPI devices FUJ02B1 and FUJ02E3 is pointless as they are not power manageable (neither _PS0 nor _PR0 is defined for any of them), which causes their power state to be inherited from their parent devices. Given the ACPI paths of these two devices (\_SB.PCI0.LPCB.FJEX, \_SB.FEXT), their parent devices are also not power manageable. These parent devices will thus have their power state initialized to ACPI_STATE_D0, which in turn causes the power state for both FUJ02B1 and FUJ02E3 to always be ACPI_STATE_D0 ("on"). Remove relevant acpi_bus_update_power() calls along with parts of debug messages that they were supposed to have an effect on.

In the case of brightness-related FUJ02B1 ACPI device, initializing the input device associated with it identically as acpi-video initializes its input device makes sense. However, using the same data for the input device associated with the FUJ02E3 ACPI device makes little sense, because the latter has nothing to do with video and assigning an arbitrary product ID to it is redundant.
