2021-03-25drm/bridge: lt9611: Fix handling of 4k panelsRobert Foss
4k requires two dsi pipes, so don't report MODE_OK when only a single pipe is configured. But rather report MODE_PANEL to signal that requirements of the panel are not being met.

0x20FF(amp global enable) register was defined as non-volatile, but it is not. Overheating, overcurrent can cause amp shutdown in hardware. 'regmap_write' compare register readback value before writing to avoid same value writing. 'regmap_read' just read cache not actual hardware value for the non-volatile register. When amp is internally shutdown by some reason, next 'AMP ON' command can be ignored because regmap think amp is already ON.

2021-03-25video: hyperv_fb: Fix a double free in hvfb_probeLv Yunlong
Function hvfb_probe() calls hvfb_getmem(), expecting upon return that info->apertures is either NULL or points to memory that should be freed by framebuffer_release(). But hvfb_getmem() is freeing the memory and leaving the pointer non-NULL, resulting in a double free if an error occurs or later if hvfb_remove() is called. Fix this by removing all kfree(info->apertures) calls in hvfb_getmem(). This will allow framebuffer_release() to free the memory, which follows the pattern of other fbdev drivers.

Use the value read from the REVID register in order to check for the presence of the device. A read of all ones is treated as if the device is not present, and hence probing is ended. This fixes an issue when running as a Xen PVH dom0, where the ACPI DSDT table is provided unmodified to dom0 and hence contains the pinctrl devices, but the MMIO region(s) containing the device registers might not be mapped in the guest physical memory map if such region(s) are not exposed on a PCI device BAR or marked as reserved in the host memory map.

2021-03-25arm64: kernel: disable CNP on CarmelRich Wiley
On NVIDIA Carmel cores, CNP behaves differently than it does on standard ARM cores. On Carmel, if two cores have CNP enabled and share an L2 TLB entry created by core0 for a specific ASID, a non-shareable TLBI from core1 may still see the shared entry. On standard ARM cores, that TLBI will invalidate the shared entry as well. This causes issues with patchsets that attempt to do local TLBIs based on cpumasks instead of broadcast TLBIs. Avoid these issues by disabling CNP support for NVIDIA Carmel cores.

2021-03-24scsi: target: pscsi: Avoid OOM in pscsi_map_sg()Martin Wilck
pscsi_map_sg() uses the variable nr_pages as a hint for bio_kmalloc() how many vector elements to allocate. If nr_pages is < BIO_MAX_PAGES, it will be reset to 0 after successful allocation of the bio. If bio_add_pc_page() fails later for whatever reason, pscsi_map_sg() tries to allocate another bio, passing nr_vecs = 0. This causes bio_add_pc_page() to fail immediately in the next call. pci_map_sg() continues to allocate zero-length bios until memory is exhausted and the kernel crashes with OOM. This can be easily observed by exporting a SATA DVD drive via pscsi. The target crashes as soon as the client tries to access the DVD LUN. In the case I analyzed, bio_add_pc_page() would fail because the DVD device's max_sectors_kb (128) was exceeded. Avoid this by simply not resetting nr_pages to 0 after allocating the bio. This way, the client receives an I/O error when it tries to send requests exceeding the devices max_sectors_kb, and eventually gets it right. The client must still limit max_sectors_kb e.g. by an udev rule if (like in my case) the driver doesn't report valid block limits, otherwise it encounters I/O errors.

During MQ enablement of the ibmvfc driver ibmvfc_wait_for_ops() was missed. This function is responsible for waiting on commands to complete that match a certain criteria such as LUN or cancel key. The implementation as is only scans the CRQ for events ignoring any sub-queues and as a result will exit successfully without doing anything when operating in MQ channelized mode. Check the MQ and channel use flags to determine which queues are applicable, and scan each queue accordingly. Note in MQ mode SCSI commands are only issued down sub-queues and the CRQ is only used for driver specific management commands. As such the CRQ events are ignored when operating in MQ mode with channels.

2021-03-24scsi: ibmvfc: Fix potential race in ibmvfc_wait_for_ops()Tyrel Datwyler
For various EH activities the ibmvfc driver uses ibmvfc_wait_for_ops() to wait for the completion of commands that match a given criteria be it cancel key, or specific LUN. With recent changes commands are completed outside the lock in bulk by removing them from the sent list and adding them to a private completion list. This introduces a potential race in ibmvfc_wait_for_ops() since the criteria for a command to be outstanding is no longer simply being on the sent list, but instead not being on the free list. Avoid this race by scanning the entire command event pool and checking that any matching command that ibmvfc needs to wait on is not already on the free list.

2021-03-25drm/nouveau/kms/nve4-nv108: Limit cursors to 128x128Lyude Paul
While Kepler does technically support 256x256 cursors, it turns out that Kepler actually has some additional requirements for scanout surfaces that we're not enforcing correctly, which aren't present on Maxwell and later. Cursor surfaces must always use small pages (4K), and overlay surfaces must always use large pages (128K). Fixing this correctly though will take a bit more work: as we'll need to add some code in prepare_fb() to move cursor FBs in large pages to small pages, and vice-versa for overlay FBs. So until we have the time to do that, just limit cursor surfaces to 128x128 - a size small enough to always default to small pages. This means small ovlys are still broken on Kepler, but it is extremely unlikely anyone cares about those anyway :).

2021-03-24ASoC: intel: atom: Stop advertising non working S24LE supportHans de Goede
The SST firmware's media and deep-buffer inputs are hardcoded to S16LE, the corresponding DAIs don't have a hw_params callback and their prepare callback also does not take the format into account. So far the advertising of non working S24LE support has not caused issues because pulseaudio defaults to S16LE, but changing pulse-audio's config to use S24LE will result in broken sound. Pipewire is replacing pulse now and pipewire prefers S24LE over S16LE when available, causing the problem of the broken S24LE support to come to the surface now.
