2021-03-29vfio/nvlink: Add missing SPAPR_TCE_IOMMU dependsJason Gunthorpe
Compiling the nvlink stuff relies on the SPAPR_TCE_IOMMU otherwise there are compile errors: drivers/vfio/pci/vfio_pci_nvlink2.c:101:10: error: implicit declaration of function 'mm_iommu_put' [-Werror,-Wimplicit-function-declaration] ret = mm_iommu_put(data->mm, data->mem); As PPC only defines these functions when the config is set. Previously this wasn't a problem by chance as SPAPR_TCE_IOMMU was the only IOMMU that could have satisfied IOMMU_API on POWERNV.

2021-03-29PM: runtime: Fix race getting/putting suppliers at probeAdrian Hunter
pm_runtime_put_suppliers() must not decrement rpm_active unless the consumer is suspended. That is because, otherwise, it could suspend suppliers for an active consumer. That can happen as follows: static int driver_probe_device(struct device_driver *drv, struct device *dev) { int ret = 0; if (!device_is_registered(dev)) return -ENODEV; dev->can_match = true; pr_debug("bus: '%s': %s: matched device %s with driver %s\n", drv->bus->name, __func__, dev_name(dev), drv->name); pm_runtime_get_suppliers(dev); if (dev->parent) pm_runtime_get_sync(dev->parent); At this point, dev can runtime suspend so rpm_put_suppliers() can run, rpm_active becomes 1 (the lowest value). pm_runtime_barrier(dev); if (initcall_debug) ret = really_probe_debug(dev, drv); else ret = really_probe(dev, drv); Probe callback can have runtime resumed dev, and then runtime put so dev is awaiting autosuspend, but rpm_active is 2. pm_request_idle(dev); if (dev->parent) pm_runtime_put(dev->parent); pm_runtime_put_suppliers(dev); Now pm_runtime_put_suppliers() will put the supplier i.e. rpm_active 2 -> 1, but consumer can still be active. return ret; } Fix by checking the runtime status. For any status other than RPM_SUSPENDED, rpm_active can be considered to be "owned" by rpm_[get/put]_suppliers() and pm_runtime_put_suppliers() need do nothing.

2021-03-29ACPI: tables: x86: Reserve memory occupied by ACPI tablesRafael J. Wysocki
The following problem has been reported by George Kennedy: Since commit 7fef431be9c9 ("mm/page_alloc: place pages to tail in __free_pages_core()") the following use after free occurs intermittently when ACPI tables are accessed. BUG: KASAN: use-after-free in ibft_init+0x134/0xc49 Read of size 4 at addr ffff8880be453004 by task swapper/0/1 CPU: 3 PID: 1 Comm: swapper/0 Not tainted 5.12.0-rc1-7a7fd0d #1 Call Trace: dump_stack+0xf6/0x158 print_address_description.constprop.9+0x41/0x60 kasan_report.cold.14+0x7b/0xd4 __asan_report_load_n_noabort+0xf/0x20 ibft_init+0x134/0xc49 do_one_initcall+0xc4/0x3e0 kernel_init_freeable+0x5af/0x66b kernel_init+0x16/0x1d0 ret_from_fork+0x22/0x30 ACPI tables mapped via kmap() do not have their mapped pages reserved and the pages can be "stolen" by the buddy allocator. Apparently, on the affected system, the ACPI table in question is not located in "reserved" memory, like ACPI NVS or ACPI Data, that will not be used by the buddy allocator, so the memory occupied by that table has to be explicitly reserved to prevent the buddy allocator from using it. In order to address this problem, rearrange the initialization of the ACPI tables on x86 to locate the initial tables earlier and reserve the memory occupied by them. The other architectures using ACPI should not be affected by this change.

This reverts commit 048eb908a1f2 ("soc: qcom-geni-se: Add interconnect support to fix earlycon crash") ICC core and platforms drivers supports sync_state feature, which ensures that the default ICC BW votes from the bootloader is not removed until all it's consumers are probes. The proxy votes were needed in case other QUP child drivers I2C, SPI probes before UART, they can turn off the QUP-CORE clock which is shared resources for all QUP driver, this causes unclocked access to HW from earlycon. Given above support from ICC there is no longer need to maintain proxy votes on QUP-CORE ICC node from QUP wrapper driver for early console usecase, the default votes won't be removed until real console is probed.

2021-03-26usb: dwc2: Prevent core suspend when port connection flag is 0Artur Petrosyan
In host mode port connection status flag is "0" when loading the driver. After loading the driver system asserts suspend which is handled by "_dwc2_hcd_suspend()" function. Before the system suspend the port connection status is "0". As result need to check the "port_connect_status" if it is "0", then skipping entering to suspend.

Pinephone running on Allwinner A64 fails to suspend with USB devices connected as reported by Bhushan Shah <bshah@kde.org>. Reverting commit 5fbf7a253470 ("usb: musb: fix idling for suspend after disconnect interrupt") fixes the issue.
