This patch implements Loongson VirtualiZation (LVZ) extension support
for LoongArch's TCG target. With this patch, it is now possible to start
a nested KVM-accelerated virtual machine on a TCG-emulated virtual machine.

SignKirigami (8):
  target/loongarch: Define LVZ CSR fields
  target/loongarch: Add LVZ CPU state definitions
  target/loongarch: Add LVZ translation context flags
  target/loongarch: Add LVZ guest CSR tables
  target/loongarch: Dump host CSRs with LVZ state
  target/loongarch: Add LVZ CPU runtime control
  target/loongarch: Add LVZ MMU and PTW support
  target/loongarch: Translate LVZ instructions
