[PATCH v4 00/14] target/loongarch: add LVZ support for TCG

[SignKirigami <prcups@krgm.moe>]

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 (14):
  target/loongarch: Define LVZ CSR fields
  target/loongarch: Add LVZ CPU state definitions
  target/loongarch: Add LVZ CSR metadata
  target/loongarch: Add LVZ CPU model support
  target/loongarch: Add LVZ guest interrupt state
  target/loongarch: Add LVZ guest timer support
  target/loongarch: Add LVZ VM entry and exception handling
  target/loongarch: Add LVZ guest CSR helpers
  target/loongarch: Add LVZ migration state
  target/loongarch: Add LVZ MMU and PTW support
  target/loongarch: Translate LVZ guest CSR instructions
  target/loongarch: Translate LVZ guest TLB instructions
  target/loongarch: Translate LVZ guest traps and HVC
  fix(tcg/loongarch): strip flag bits in lddir/ldpte address calculation
