An update on Loongarch: I was originally planning to send Linus a pull request with the branch with the contents from https://git.kernel.org/pub/scm/linux/kernel/git/chenhuacai/linux-loongson.git/log/?h=loongarch-next but I saw that this includes both the architecture code and some device drivers (irqchip, pci, acpi) that are essential for the kernel to actually boot. At least the irqchip driver has not passed review because it uses a nonstandard way to integrate into ACPI, and the PCI stuff may or may not be ready but has no Reviewed-by or Acked-by tags from the maintainers. I clearly don't want to bypass the subsystem maintainers on those drivers by sending a pull request for the current branch. My feeling is that there is also no point in merging a port without the drivers as it cannot work on any hardware. On the other hand, the libc submissions (glibc and musl) are currently blocked while they are waiting for the kernel port to get merged. Arnd
