Please look into sharing the similar code in target/i386/kvm.c (kvm_get_sregs), since the HAX code has some bugs (for example, HF_CPL_MASK should be SS.DPL, not CS.DPL). Paolo
Thanks. Then it seems I should put this piece of code in a common function first and then update this CL.

hax_setup_qemu_emulator reference env->efer which is updated in hax_get_msrs, so it has to be called after hax_get_msrs. This fix the bug that sometimes dump_state show 32 bits regs even in 64 bits mode.
