2018-06-27dm thin: handle running out of data space vs concurrent discardMike Snitzer1-2/+9
Discards issued to a DM thin device can complete to userspace (via fstrim) _before_ the metadata changes associated with the discards is reflected in the thinp superblock (e.g. free blocks). As such, if a user constructs a test that loops repeatedly over these steps, block allocation can fail due to discards not having completed yet: 1) fill thin device via filesystem file 2) remove file 3) fstrim From initial report, here: https://www.redhat.com/archives/dm-devel/2018-April/msg00022.html "The root cause of this issue is that dm-thin will first remove mapping and increase corresponding blocks' reference count to prevent them from being reused before DISCARD bios get processed by the underlying layers. However. increasing blocks' reference count could also increase the nr_allocated_this_transaction in struct sm_disk which makes smd->old_ll.nr_allocated + smd->nr_allocated_this_transaction bigger than smd->old_ll.nr_blocks. In this case, alloc_data_block() will never commit metadata to reset the begin pointer of struct sm_disk, because sm_disk_get_nr_free() always return an underflow value." While there is room for improvement to the space-map accounting that thinp is making use of: the reality is this test is inherently racey and will result in the previous iteration's fstrim's discard(s) completing vs concurrent block allocation, via dd, in the next iteration of the loop. No amount of space map accounting improvements will be able to allow user's to use a block before a discard of that block has completed. So the best we can really do is allow DM thinp to gracefully handle such aggressive use of all the pool's data by degrading the pool into out-of-data-space (OODS) mode. We _should_ get that behaviour already (if space map accounting didn't falsely cause alloc_data_block() to believe free space was available).. but short of that we handle the current reality that dm_pool_alloc_data_block() can return -ENOSPC.

2018-06-26PCI: controller: Move PCI_DOMAINS selection to arch KconfigLorenzo Pieralisi1-3/+0
Commit 51bc085d6454 ("PCI: Improve host drivers compile test coverage") added configuration options to allow PCI host controller drivers to be compile tested on all architectures. Some host controller drivers (eg PCIE_ALTERA) config entries select the PCI_DOMAINS config option to enable PCI domains management in the kernel. Now that host controller drivers can be compiled on all architectures, this triggers build regressions on arches that do not implement the PCI_DOMAINS required API (ie pci_domain_nr()): drivers/ata/pata_ali.c: In function 'ali_init_chipset': drivers/ata/pata_ali.c:469:38: error: implicit declaration of function 'pci_domain_nr'; did you mean 'pci_iomap_wc'? Furthemore, some software configurations (ie Jailhouse) require a PCI_DOMAINS enabled kernel to configure multiple host controllers without having an explicit dependency on the ARM platform on which they run. Make PCI_DOMAINS a visible configuration option on ARM so that software configurations that need it can manually select it and move the PCI_DOMAINS selection from PCI controllers configuration file to ARM sub-arch config entries that currently require it, fixing the issue.

2018-06-26PCI: Initialize endpoint library before controllersAlan Douglas1-3/+3
The endpoint library must be initialized before its users, which are in drivers/pci/controllers. The endpoint initialization currently depends on link order. This corrects a kernel crash when loading the Cadence EP driver, since it calls devm_pci_epc_create() and this is only valid once the endpoint library has been initialized.

2018-06-26PCI: shpchp: Manage SHPC unconditionally on non-ACPI systemsBjorn Helgaas1-1/+9
An SHPC can be operated either by platform firmware or by the OS. The OS uses a host bridge ACPI _OSC method to negotiate for control of SHPC. If firmware wants to prevent an OS from operating an SHPC, it must supply an _OSC method that declines to grant SHPC ownership to the OS. If acpi_pci_find_root() returns NULL, it means there's no ACPI host bridge device (PNP0A03 or PNP0A08) and hence no _OSC method, so the OS is always allowed to manage the SHPC. Fix a NULL pointer dereference when CONFIG_ACPI=y but the current hardware/firmware platform doesn't support ACPI. In that case, acpi_get_hp_hw_control_from_firmware() is implemented but acpi_pci_find_root() returns NULL.

2018-06-25usb: typec: ucsi: Fix for incorrect status data issueHeikki Krogerus1-0/+13
According to UCSI Specification, Connector Change Event only means a change in the Connector Status and Operation Mode fields of the STATUS data structure. So any other change should create another event. Unfortunately on some platforms the firmware acting as PPM (platform policy manager - usually embedded controller firmware) still does not report any other status changes if there is a connector change event. So if the connector power or data role was changed when a device was plugged to the connector, the driver does not get any indication about that. The port will show wrong roles if that happens. To fix the issue, always checking the data and power role together with a connector change event.

2018-06-25usb: typec: ucsi: acpi: Workaround for cache mode issueHeikki Krogerus1-0/+5
This fixes an issue where the driver fails with an error: ioremap error for 0x3f799000-0x3f79a000, requested 0x2, got 0x0 On some platforms the UCSI ACPI mailbox SystemMemory Operation Region may be setup before the driver has been loaded. That will lead into the driver failing to map the mailbox region, as it has been already marked as write-back memory. acpi_os_ioremap() for x86 uses ioremap_cache() unconditionally. When the issue happens, the embedded controller has a pending query event for the UCSI notification right after boot-up which causes the operation region to be setup before UCSI driver has been loaded. The fix is to notify acpi core that the driver is about to access memory region which potentially overlaps with an operation region right before mapping it. acpi_release_memory() will check if the memory has already been setup (mapped) by acpi core, and deactivate it (unmap) if it has. The driver is then able to map the memory with ioremap_nocache() and set the memtype to uncached for the region.

2018-06-25acpi: Add helper for deactivating memory regionHeikki Krogerus1-0/+72
Sometimes memory resource may be overlapping with SystemMemory Operation Region by design, for example if the memory region is used as a mailbox for communication with a firmware in the system. One occasion of such mailboxes is USB Type-C Connector System Software Interface (UCSI). With regions like that, it is important that the driver is able to map the memory with the requirements it has. For example, the driver should be allowed to map the memory as non-cached memory. However, if the operation region has been accessed before the driver has mapped the memory, the memory has been marked as write-back by the time the driver is loaded. That means the driver will fail to map the memory if it expects non-cached memory. To work around the problem, introducing helper that the drivers can use to temporarily deactivate (unmap) SystemMemory Operation Regions that overlap with their IO memory.

2018-06-25xhci: Fix kernel oops in trace_xhci_free_virt_deviceZhengjun Xing2-7/+33
commit 44a182b9d177 ("xhci: Fix use-after-free in xhci_free_virt_device") set dev->udev pointer to NULL in xhci_free_dev(), it will cause kernel panic in trace_xhci_free_virt_device. This patch reimplement the trace function trace_xhci_free_virt_device, remove dev->udev dereference and added more useful parameters to show in the trace function,it also makes sure dev->udev is not NULL before calling trace_xhci_free_virt_device. This issue happened when xhci-hcd trace is enabled and USB devices hot plug test. Original use-after-free patch went to stable so this needs so be applied there as well.

2018-06-25xhci: Fix perceived dead host due to runtime suspend race with event handlerMathias Nyman2-3/+41
Don't rely on event interrupt (EINT) bit alone to detect pending port change in resume. If no change event is detected the host may be suspended again, oterwise roothubs are resumed. There is a lag in xHC setting EINT. If we don't notice the pending change in resume, and the controller is runtime suspeded again, it causes the event handler to assume host is dead as it will fail to read xHC registers once PCI puts the controller to D3 state.

This happens on machines where the mpu6050 is enumerated through ACPI and an older Interrupt type ACPI resource is used for the interrupt, rather then a GpioInt type type, causing the mpu6050 driver to no longer work there. This happens on e.g. the Asus T100TA. This commits makes the mpu6050 fallback to the old IRQF_TRIGGER_RISING default if the irq-type is not setup, fixing this.
