[PATCH v4 2/6] usb: dwc3: gadget: cancel requests instead of release after missed isoc

by Dan Vacura

From: Jeff Vanhoof <qjv001(a)motorola.com> arm-smmu related crashes seen after a Missed ISOC interrupt when no_interrupt=1 is used. This can happen if the hardware is still using the data associated with a TRB after the usb_request's ->complete call has been made. Instead of immediately releasing a request when a Missed ISOC interrupt has occurred, this change will add logic to cancel the request instead where it will eventually be released when the END_TRANSFER command has completed. This logic is similar to some of the cleanup done in dwc3_gadget_ep_dequeue.

[PATCH] power: supply: rk817: Add missing module alias

by Nicolas Frattaroli

Similar to the rk817 codec alias that was missing, the rk817 charger driver is missing a module alias as well. This absence prevents the driver from autoprobing on OF systems when it is built as a module. Add the right MODULE_ALIAS to fix this.

[PATCH v3] mmc: sdhci-pci-gli: fix LPM negotiation so x86/S0ix SoCs can suspend

by Sven van Ashbrook

To improve the r/w performance of GL9763E, the current driver inhibits LPM negotiation while the device is active. This prevents a large number of SoCs from suspending, notably x86 systems which commonly use S0ix as the suspend mechanism - for example, Intel Alder Lake and Raptor Lake processors. Failure description: 1. Userspace initiates s2idle suspend (e.g. via writing to /sys/power/state) 2. This switches the runtime_pm device state to active, which disables LPM negotiation, then calls the "regular" suspend callback 3. With LPM negotiation disabled, the bus cannot enter low-power state 4. On a large number of SoCs, if the bus not in a low-power state, S0ix cannot be entered, which in turn prevents the SoC from entering suspend. Fix by re-enabling LPM negotiation in the device's suspend callback.

[PATCH v2] vhost: Allow null msg.size on VHOST_IOTLB_INVALIDATE

by Eric Auger

Commit e2ae38cf3d91 ("vhost: fix hung thread due to erroneous iotlb entries") Forbade vhost iotlb msg with null size to prevent entries with size = start = 0 and last = ULONG_MAX to end up in the iotlb. Then commit 95932ab2ea07 ("vhost: allow batching hint without size") only applied the check for VHOST_IOTLB_UPDATE and VHOST_IOTLB_INVALIDATE message types to fix a regression observed with batching hit. Still, the introduction of that check introduced a regression for some users attempting to invalidate the whole ULONG_MAX range by setting the size to 0. This is the case with qemu/smmuv3/vhost integration which does not work anymore. It Looks safe to partially revert the original commit and allow VHOST_IOTLB_INVALIDATE messages with null size. vhost_iotlb_del_range() will compute a correct end iova.

[PATCH v2 1/2] maple_tree: Disable mas_wr_append() when other readers are possible

by Liam R. Howlett

The current implementation of append may cause duplicate data and/or incorrect ranges to be returned to a reader during an update. Although this has not been reported or seen, disable the append write operation while the tree is in rcu mode out of an abundance of caution. During the analysis of the mas_next_slot() the following was artificially created by separating the writer and reader code: Writer: reader: mas_wr_append set end pivot updates end metata Detects write to last slot last slot write is to start of slot store current contents in slot overwrite old end pivot mas_next_slot(): read end metadata read old end pivot return with incorrect range store new value Alternatively: Writer: reader: mas_wr_append set end pivot updates end metata Detects write to last slot last lost write to end of slot store value mas_next_slot(): read end metadata read old end pivot read new end pivot return with incorrect range set old end pivot There may be other accesses that are not safe since we are now updating both metadata and pointers, so disabling append if there could be rcu readers is the safest action.
