LoongArch32 Support Begins Taking Shape In Linux 6.19, GCC 16

The LoongArch CPU architecture changes have been merged for the Linux 6.19 merge window. This domestic Chinese CPU architecture inspired by MIPS and RISC-V began with 64-bit LoongArch64 but with Linux 6.19 the foundation is being laid for LoongArch32 as a 32-bit variant.

While most CPU architectures went from a 32-bit to 64-bit world, Loongson is working back from 64-bit to 32-bit. They've been working on the LoongArch32 ABI and with Linux 6.19 that initial kernel port is being wired up.
