2019-09-11iommu/vt-d: Declare Broadwell igfx dmar support snafuChris Wilson
Despite the widespread and complete failure of Broadwell integrated graphics when DMAR is enabled, known over the years, we have never been able to root cause the issue. Instead, we let the failure undermine our confidence in the iommu system itself when we should be pushing for it to be always enabled. Quirk away Broadwell and remove the rotten apple.

2019-09-11iommu/vt-d: Use bounce buffer for untrusted devicesLu Baolu
The Intel VT-d hardware uses paging for DMA remapping. The minimum mapped window is a page size. The device drivers may map buffers not filling the whole IOMMU window. This allows the device to access to possibly unrelated memory and a malicious device could exploit this to perform DMA attacks. To address this, the Intel IOMMU driver will use bounce pages for those buffers which don't fill whole IOMMU pages.

As the register names for both controllers are the same and the 36 1.8V GPIOs and the first 36 of the 3.3V GPIOs are all bidirectional, we can use the same configuration struct and use the ngpio property to differentiate between the two sets of GPIOs.

2019-09-11gpiolib: acpi: Add gpiolib_acpi_run_edge_events_on_boot option and blacklistHans de Goede
Another day; another DSDT bug we need to workaround... Since commit ca876c7483b6 ("gpiolib-acpi: make sure we trigger edge events at least once on boot") we call _AEI edge handlers at boot. In some rare cases this causes problems. One example of this is the Minix Neo Z83-4 mini PC, this device has a clear DSDT bug where it has some copy and pasted code for dealing with Micro USB-B connector host/device role switching, while the mini PC does not even have a micro-USB connector. This code, which should not be there, messes with the DDC data pin from the HDMI connector (switching it to GPIO mode) breaking HDMI support. To avoid problems like this, this commit adds a new gpiolib_acpi.run_edge_events_on_boot kernel commandline option, which allows disabling the running of _AEI edge event handlers at boot. The default value is -1/auto which uses a DMI based blacklist, the initial version of this blacklist contains the Neo Z83-4 fixing the HDMI breakage.

2019-09-11cfg80211: Purge frame registrations on iftype changeDenis Kenzior
Currently frame registrations are not purged, even when changing the interface type. This can lead to potentially weird situations where frames possibly not allowed on a given interface type remain registered due to the type switching happening after registration. The kernel currently relies on userspace apps to actually purge the registrations themselves, this is not something that the kernel should rely on. Add a call to cfg80211_mlme_purge_registrations() to forcefully remove any registrations left over prior to switching the iftype.
