[ Upstream commit dcf768b0 ] I've spotted another Chicony PixArt mouse in the wild, which requires HID_QUIRK_ALWAYS_POLL quirk, otherwise it disconnects each minute. USB ID of this device is 0x04f2:0x0939. We've introduced quirks like this for other models before, so lets add this mouse too.

[ Upstream commit c1887159 ] __startup_64() uses fixup_pointer() to access global variables in a position-independent fashion. Access to next_early_pgt was wrapped into the helper, but one instance in the 5-level paging branch was missed. GCC generates a R_X86_64_PC32 PC-relative relocation for the access which doesn't trigger the issue, but Clang emmits a R_X86_64_32S which leads to an invalid memory access and system reboot.

[ Upstream commit 81c7ed29 ] A kernel which boots in 5-level paging mode crashes in a small percentage of cases if KASLR is enabled. This issue was tracked down to the case when the kernel image unpacks in a way that it crosses an 1G boundary. The crash is caused by an overrun of the PMD page table in __startup_64() and corruption of P4D page table allocated next to it. This particular issue is not visible with 4-level paging as P4D page tables are not used. But the P4D and the PUD calculation have similar problems. The PMD index calculation is wrong due to operator precedence, which fails to confine the PMDs in the PMD array on wrap around. The P4D calculation for 5-level paging and the PUD calculation calculate the first index correctly, but then blindly increment it which causes the same issue when a kernel image is located across a 512G and for 5-level paging across a 46T boundary. This wrap around mishandling was introduced when these parts moved from assembly to C. Restore it to the correct behaviour. Fixes: c88d7150 ("x86/boot/64: Rewrite startup_64() in C") Signed-off-by:

[ Upstream commit a0651926 ] For the first call to realloc_argv() in dm_split_args(), old_argv is NULL and size is zero. Then memcpy is called, with the NULL old_argv as the source argument and a zero size argument.

[ Upstream commit 6dbc6e6f ] Currently probing of the mcp23s08 results in an error message "detected irqchip that is shared with multiple gpiochips: please fix the driver" This is due to the following: Call to mcp23s08_irqchip_setup() with call hierarchy: mcp23s08_irqchip_setup() gpiochip_irqchip_add_nested() gpiochip_irqchip_add_key() gpiochip_set_irq_hooks() Call to devm_gpiochip_add_data() with call hierarchy: devm_gpiochip_add_data() gpiochip_add_data_with_key() gpiochip_add_irqchip() gpiochip_set_irq_hooks() The gpiochip_add_irqchip() returns immediately if there isn't a irqchip but we added a irqchip due to the previous mcp23s08_irqchip_setup() call. So it calls gpiochip_set_irq_hooks() a second time.

[ Upstream commit a483fcab ] Starting with ACPI 6.2 bits 1 and 2 of the BGRT status field are no longer reserved. These bits are now used to indicate if the image needs to be rotated before being displayed. The first device using these bits has now shown up (the GPD MicroPC) and the reserved bits check causes us to reject the valid BGRT table on this device. Rather then changing the reserved bits check, allowing only the 2 new bits, instead just completely remove it so that we do not end up with a similar problem when more bits are added in the future.

[ Upstream commit a050fa54 ] When we run several VMs with PCI passthrough and GICv4 enabled, not pinning vCPUs, we will occasionally see below warnings in dmesg: ITS queue timeout (65440 65504 480) ITS cmd its_build_vmovp_cmd failed The reason for the above issue is that in BUILD_SINGLE_CMD_FUNC: 1. Post the write command. 2. Release the lock. 3. Start to read GITS_CREADR to get the reader pointer. 4. Compare the reader pointer to the target pointer. 5. If reader pointer does not reach the target, sleep 1us and continue to try. If we have several processors running the above concurrently, other CPUs will post write commands while the 1st CPU is waiting the completion. So we may have below issue: phase 1: ---rd_idx-----from_idx-----to_idx--0--------- wait 1us: phase 2: --------------from_idx-----to_idx--0-rd_idx-- That is the rd_idx may fly ahead of to_idx, and if in case to_idx is near the wrap point, rd_idx will wrap around. So the below condition will not be met even after 1s: if (from_idx < to_idx && rd_idx >= to_idx) There is another theoretical issue. For a slow and busy ITS, the initial rd_idx may fall behind from_idx a lot, just as below: ---rd_idx---0--from_idx-----to_idx----------- This will cause the wait function exit too early. Actually, it does not make much sense to use from_idx to judge if to_idx is wrapped, but we need a initial rd_idx when lock is still acquired, and it can be used to judge whether to_idx is wrapped and the current rd_idx is wrapped. We switch to a method of calculating the delta of two adjacent reads and accumulating it to get the sum, so that we can get the real rd_idx from the wrapped value even when the queue is almost full.

[ Upstream commit 26d65140 ] Amlogic's vendor kernel defines an OPP for the GPU on Meson8b boards with a voltage of 1.15V. It turns out that the vendor kernel relies on the bootloader to set up the voltage. The bootloader however sets a fixed voltage of 1.10V.

The VDDEE regulator supplies the Mali GPU. It's basically a copy of the VCCK (CPU supply) which means it's limited to 0.86V to 1.14V.

Unfortunately, the code does the opposite: it expressly permits sysfs fw loading if security_kernel_load_data( LOADING_FIRMWARE) returns -EACCES.

commit 83b44fe3 upstream. The cacheinfo structures are alloced/freed by cpu online/offline callbacks. Originally these were only used by sysfs to expose the cache topology to user space. Without any in-kernel dependencies CPUHP_AP_ONLINE_DYN was an appropriate choice. resctrl has started using these structures to identify CPUs that share a cache. It updates its 'domain' structures from cpu online/offline callbacks. These depend on the cacheinfo structures (resctrl_online_cpu()->domain_add_cpu()->get_cache_id()-> get_cpu_cacheinfo()). These also run as CPUHP_AP_ONLINE_DYN. Now that there is an in-kernel dependency, move the cacheinfo work earlier so we know its done before resctrl's CPUHP_AP_ONLINE_DYN work runs.

commit d17ba0f6 upstream. Driver does not want to keep packets in Tx queue when link is lost. But present code only reset NIC to flush them, but does not prevent queuing new packets. Moreover reset sequence itself could generate new packets via netconsole and NIC falls into endless reset loop. This patch wakes Tx queue only when NIC is ready to send packets. This is proper fix for problem addressed by commit 0f9e980b ("e1000e: fix cyclic resets at link up with active tx"). Signed-off-by:

commit fbd6b250 upstream. An earlier patch I sent reduced the stack usage enough to get below the warning limit, and I could show this was safe, but with GCC_PLUGIN_STRUCTLEAK_BYREF_ALL, it gets worse again because large stack variables in the same function no longer overlap: drivers/staging/rtl8712/rtl871x_ioctl_linux.c: In function 'translate_scan.isra.2': drivers/staging/rtl8712/rtl871x_ioctl_linux.c:322:1: error: the frame size of 1200 bytes is larger than 1024 bytes [-Werror=frame-larger-than=] Split out the largest two blocks in the affected function into two separate functions and mark those noinline_for_stack.

commit a26be06d upstream. The change to mapping V4L2 to MMAL buffers 1:1 didn't handle the condition we get with raw pixel buffers (eg YUV and RGB) direct from the camera's stills port. That sends the pixel buffer and then an empty buffer with the EOS flag set. The EOS buffer wasn't handled and returned an error up the stack. Handle the condition correctly by returning it to the component if streaming, or returning with an error if stopping streaming.

commit bb8e9700 upstream. Before commit "staging: bcm2835-camera: Remove V4L2/MMAL buffer remapping" there was a need to ensure that there were sufficient buffers supplied from the user to cover those being sent to the VPU (always 1). Now the buffers are linked 1:1 between MMAL and V4L2, therefore there is no need for that check, and indeed it is wrong as there is no need to submit all the buffers before starting streaming.

commit 70ec64cc upstream. With the recent change to match MMAL and V4L2 buffers there is a need to wait for all MMAL buffers to be returned during stop_streaming. Fixes: 93841670 ("staging: bcm2835-camera: Remove V4L2/MMAL buffer remapping") Signed-off-by:

commit 8dedab29 upstream. The commit "staging: bcm2835-camera: Replace open-coded idr with a struct idr." replaced an internal implementation of an idr with the standard functions and a spinlock. idr_alloc(GFP_KERNEL) can sleep whilst calling kmem_cache_alloc to allocate the new node, but this is not valid whilst in an atomic context due to the spinlock. There is no need for this to be a spinlock as a standard mutex is sufficient. Fixes: 950fd867 ("staging: bcm2835-camera: Replace open-coded idr with a struct idr.") Signed-off-by:

commit 77cf3f5d upstream. The killable version of wait_event() is meant to be used on situations where it should not fail at all costs, but still have the convenience of being able to kill it if really necessary. Wait events in VCHIQ doesn't fit this criteria, as it's mainly used as an interface to V4L2 and ALSA devices. Fixes: 852b2876 ("staging: vchiq: rework remove_event handling") Signed-off-by:
