2020-12-23net: ipa: clear pending interrupts before enablingAlex Elder
We enable the completion interrupt for channel or event ring commands only when we issue them. The interrupt is disabled after the interrupt has fired, or after we have timed out waiting for it. If we time out, the command could complete after the interrupt has been disabled, causing a state change in the channel or event ring. The interrupt associated with that state change would be delivered the next time the completion interrupt is enabled. To avoid previous command completions interfering with new commands, clear all pending completion interrupts before re-enabling them for a new command.

2020-12-23drm/amd/display: Fix memory leaks in S3 resumeStylon Wang
EDID parsing in S3 resume pushes new display modes to probed_modes list but doesn't consolidate to actual mode list. This creates a race condition when amdgpu_dm_connector_ddc_get_modes() re-initializes the list head without walking the list and results in memory leak.

2020-12-23KVM: arm64: Move double-checked lock to kvm_vgic_map_resources()Alexandru Elisei
kvm_vgic_map_resources() is called when a VCPU if first run and it maps all the VGIC MMIO regions. To prevent double-initialization, the VGIC uses the ready variable to keep track of the state of resources and the global KVM mutex to protect against concurrent accesses. After the lock is taken, the variable is checked again in case another VCPU took the lock between the current VCPU reading ready equals false and taking the lock. The double-checked lock pattern is spread across four different functions: in kvm_vcpu_first_run_init(), in kvm_vgic_map_resource() and in vgic_{v2,v3}_map_resources(), which makes it hard to reason about and introduces minor code duplication. Consolidate the checks in kvm_vgic_map_resources(), where the lock is taken. No functional change intended.

2020-12-23KVM: arm64: arch_timer: Remove VGIC initialization checkAlexandru Elisei
kvm_timer_enable() is called in kvm_vcpu_first_run_init() after kvm_vgic_map_resources() if the VGIC wasn't ready. kvm_vgic_map_resources() is the only place where kvm->arch.vgic.ready is set to true. For a v2 VGIC, kvm_vgic_map_resources() will attempt to initialize the VGIC and set the initialized flag. For a v3 VGIC, kvm_vgic_map_resources() will return an error code if the VGIC isn't already initialized. The end result is that if we've reached kvm_timer_enable(), the VGIC is initialzed and ready and vgic_initialized() will always be true, so remove this check.

2020-12-23KVM: Documentation: Add arm64 KVM_RUN error codesAlexandru Elisei
The API documentation states that general error codes are not detailed, but errors with specific meanings are. On arm64, KVM_RUN can return error numbers with a different meaning than what is described by POSIX or the C99 standard (as taken from man 3 errno). Absent from the newly documented error codes is ERANGE which can be returned when making a change to the EL2 stage 1 tables if the address is larger than the largest supported input address. Assuming no bugs in the implementation, that is not possible because the input addresses which are mapped are the result of applying the macro kern_hyp_va() on kernel virtual addresses.

2020-12-22MAINTAINERS: remove names from mailing list maintainersJakub Kicinski
When searching for inactive maintainers it's useful to filter out mailing list addresses. Such "maintainers" will obviously never feature in a "From:" line of an email or a review tag. Since "L:" entries only provide the address of a mailing list without a fancy name extend this pattern to "M:" entries. Alternatively we could reserve M: entries for humans only and move the fake "maintainers" to L:. While I'd personally prefer to reserve M: for humans only, I'm not 100% that's a great choice either, given most L: entries are in fact open mailing lists with public archives.

2020-12-22net: stmmac: dwmac-meson8b: ignore the second clock inputMartin Blumenstingl
The dwmac glue registers on Amlogic Meson8b and newer SoCs has two clock inputs: - Meson8b and Meson8m2: MPLL2 and MPLL2 (the same parent is wired to both inputs) - GXBB, GXL, GXM, AXG, G12A, G12B, SM1: FCLK_DIV2 and MPLL2 All known vendor kernels and u-boots are using the first input only. We let the common clock framework automatically choose the "right" parent. For some boards this causes a problem though, specificially with G12A and newer SoCs. The clock input is used for generating the 125MHz RGMII TX clock. For the two input clocks this means on G12A: - FCLK_DIV2: 999999985Hz / 8 = 124999998.125Hz - MPLL2: 499999993Hz / 4 = 124999998.25Hz In theory MPLL2 is the "better" clock input because it's gets us 0.125Hz closer to the requested frequency than FCLK_DIV2. In reality however there is a resource conflict because MPLL2 is needed to generate some of the audio clocks. dwmac-meson8b probes first and sets up the clock tree with MPLL2. This works fine until the audio driver comes and "steals" the MPLL2 clocks and configures it with it's own rate (294909637Hz). The common clock framework happily changes the MPLL2 rate but does not reconfigure our RGMII TX clock tree, which then ends up at 73727409Hz, which is more than 40% off the requested 125MHz. Don't use the second clock input for now to force the common clock framework to always select the first parent. This mimics the behavior from the vendor driver and fixes the clock resource conflict with the audio driver on G12A boards. Once the common clock framework can handle this situation this change can be reverted again.

2020-12-22dt-bindings: Drop redundant maxItems/itemsRob Herring
'maxItems' equal to the 'items' list length is redundant. 'maxItems' is preferred for a single entry while greater than 1 should have an 'items' list.

2020-12-22io_uring: hold uring_lock while completing failed polled io in ↵Xiaoguang Wang
io_wq_submit_work() io_iopoll_complete() does not hold completion_lock to complete polled io, so in io_wq_submit_work(), we can not call io_req_complete() directly, to complete polled io, otherwise there maybe concurrent access to cqring, defer_list, etc, which is not safe. Commit dad1b1242fd5 ("io_uring: always let io_iopoll_complete() complete polled io") has fixed this issue, but Pavel reported that IOPOLL apart from rw can do buf reg/unreg requests( IORING_OP_PROVIDE_BUFFERS or IORING_OP_REMOVE_BUFFERS), so the fix is not good. Given that io_iopoll_complete() is always called under uring_lock, so here for polled io, we can also get uring_lock to fix this issue.
