Merge tag 'loongarch-kvm-6.14' of git://git.kernel.org/pub/scm/linux/kernel/git/chenhuacai/linux-loongson into HEAD
LoongArch KVM changes for v6.14 1. Clear LLBCTL if secondary mmu mapping changed. 2. Add hypercall service support for usermode VMM. This is a really small changeset, because the Chinese New Year (Spring Festival) is coming. Happy New Year!
