Boot-tested under QEMU for Rust x86_64, arm64 and riscv64; built-tested for loongarch64 and arm32: Tested-by: Miguel Ojeda I found a build error for all builds with Nova: error[E0405]: cannot find trait `FromBytes` in this scope --> drivers/gpu/nova-core/vbios.rs:398:13 | 398 | unsafe impl FromBytes for BitToken {} | ^^^^^^^^^ not found in this scope | help: consider importing this trait | 5 + use kernel::transmute::FromBytes; | The reason is that the trait is not imported (and then the function does not exist in 6.18.y, i.e. `from_bytes_copy_prefix()`). I suggest dropping commit d8fa174e21c8 ("gpu: nova-core: vbios: read BitToken using FromBytes") for now -- it was not marked for stable, and as far as I know, there are no production users of Nova, especially in stable kernels. With that reverted, 6.18.y is fine for me for all builds. If we want to fix the bug, then we may want a custom minimal patch. Same applies for -rc1.
