2021-08-05drm/amd/display: workaround for hard hang on HPD on native DPQingqing Zhuo
[Why] HPD disable and enable sequences are not mutually exclusive on Linux. For HPDs that spans over 1s (i.e. HPD low = 1s), part of the disable sequence (specifically, a request to SMU to lower refclk) could come right before the call to PHY enable, causing DMUB to access an unresponsive PHY and thus a hard hang on the system. [How] Disable 48mhz refclk off on native DP.

2021-08-05usb: dwc3: gadget: Avoid runtime resume if disabling pullupWesley Cheng
If the device is already in the runtime suspended state, any call to the pullup routine will issue a runtime resume on the DWC3 core device. If the USB gadget is disabling the pullup, then avoid having to issue a runtime resume, as DWC3 gadget has already been halted/stopped. This fixes an issue where the following condition occurs: usb_gadget_remove_driver() -->usb_gadget_disconnect() -->dwc3_gadget_pullup(0) -->pm_runtime_get_sync() -> ret = 0 -->pm_runtime_put() [async] -->usb_gadget_udc_stop() -->dwc3_gadget_stop() -->dwc->gadget_driver = NULL ... dwc3_suspend_common() -->dwc3_gadget_suspend() -->DWC3 halt/stop routine skipped, driver_data == NULL This leads to a situation where the DWC3 gadget is not properly stopped, as the runtime resume would have re-enabled EP0 and event interrupts, and since we avoided the DWC3 gadget suspend, these resources were never disabled.

2021-08-05usb: dwc3: gadget: Use list_replace_init() before traversing listsWesley Cheng
The list_for_each_entry_safe() macro saves the current item (n) and the item after (n+1), so that n can be safely removed without corrupting the list. However, when traversing the list and removing items using gadget giveback, the DWC3 lock is briefly released, allowing other routines to execute. There is a situation where, while items are being removed from the cancelled_list using dwc3_gadget_ep_cleanup_cancelled_requests(), the pullup disable routine is running in parallel (due to UDC unbind). As the cleanup routine removes n, and the pullup disable removes n+1, once the cleanup retakes the DWC3 lock, it references a request who was already removed/handled. With list debug enabled, this leads to a panic. Ensure all instances of the macro are replaced where gadget giveback is used. Example call stack: Thread#1: __dwc3_gadget_ep_set_halt() - CLEAR HALT -> dwc3_gadget_ep_cleanup_cancelled_requests() ->list_for_each_entry_safe() ->dwc3_gadget_giveback(n) ->dwc3_gadget_del_and_unmap_request()- n deleted[cancelled_list] ->spin_unlock ->Thread#2 executes ... ->dwc3_gadget_giveback(n+1) ->Already removed! Thread#2: dwc3_gadget_pullup() ->waiting for dwc3 spin_lock ... ->Thread#1 released lock ->dwc3_stop_active_transfers() ->dwc3_remove_requests() ->fetches n+1 item from cancelled_list (n removed by Thread#1) ->dwc3_gadget_giveback() ->dwc3_gadget_del_and_unmap_request()- n+1 deleted[cancelled_list] ->spin_unlock Fix this condition by utilizing list_replace_init(), and traversing through a local copy of the current elements in the endpoint lists. This will also set the parent list as empty, so if another thread is also looping through the list, it will be empty on the next iteration.

2021-08-04cpufreq: Replace deprecated CPU-hotplug functionsSebastian Andrzej Siewior
The functions get_online_cpus() and put_online_cpus() have been deprecated during the CPU hotplug rework. They map directly to cpus_read_lock() and cpus_read_unlock(). Replace deprecated CPU-hotplug functions with the official version. The behavior remains unchanged. Signed-off-by: Sebastian Andrzej Siewior <bigeasy@linutronix.de> Signed-off-by: Rafael J.

The software mapping for GPIO, which initially comes from Microsoft, is subject to change by respective Windows and firmware developers.

2021-08-04s390/dasd: fix use after free in dasd path handlingStefan Haberland
When new configuration data is obtained after a path event it is stored in the per path array. The old data needs to be freed. The first valid configuration data is also referenced in the device private structure to identify the device. When the old per path configuration data was freed the device still pointed to the already freed data leading to a use after free. Fix by replacing also the device configuration data with the newly obtained one before the old data gets freed.

In case of this switch we work with 32bit registers on top of 16bit bus. Some registers (for example access to forwarding database) have trigger bit on the first 16bit half of request and the result + configuration of request in the second half. Without this patch, we would trigger database operation and overwrite result in one run. To make it work properly, we should do the second part of transfer before the first one is done. So far, this rule seems to work for all registers on this switch.

If hns_roce_cmd_use_events() fails then it means that the poll_sem is not obtained, but the poll_sem is released in hns_roce_cmd_use_polling(), this will cause an unlock problem. This is the static checker warning: drivers/infiniband/hw/hns/hns_roce_main.c:926 hns_roce_init() error: double unlocked '&hr_dev->cmd.poll_sem' (orig line 879) Event mode and polling mode are mutually exclusive and resources are separated, so there is no need to process polling mode resources in event mode.

2021-08-03cpuidle: teo: Fix alternative idle state lookupRafael J. Wysocki
There are three mistakes in the loop in teo_select() that is looking for an alternative candidate idle state. First, it should walk all of the idle states shallower than the current candidate one, including all of the disabled ones, but it terminates after the first enabled idle state. Second, it should not terminate its last step if idle state 0 is disabled (which is related to the first issue). Finally, it may return the current alternative candidate idle state prematurely if the time span criterion is not met by the idle state under consideration at the moment. To address the issues mentioned above, make the loop in question walk all of the idle states shallower than the current candidate idle state all the way down to idle state 0 and rearrange the checks in it.
