Hi Chang,

I tested this series with QEMU master, and no regression was found.

my tests include:

1) Check APX enumeration & XSTATE in L1 & L2 VM.
2) (with AI help) Collect instruction test cases from LLVM/GCC and
   create some new, then test them in L1 & L2 VM.
3) Expand the selftest to cover additional KVM instruction-emulator
   cases.

All tests are passed at my side, so,
