I’m still occasionally testing 32-bit MIPS KVM support with MIPS P5600.
It works just fine so there is no need for further maintenance work.
I’d be sad to see the support go but I can live with it.
There are commercial users for MIPS 32 KVM but they’re all running customized
downstream QEMU so I guess it’s fine.
