Here new structure CPUSysState is added in CPULoongArchState, CSR
registers are move in CPUSysState. In later with LVZ supported, there
will
be two copied of CSR registers, so it is simply to add CPUSysState array.
Also new field curState is added which points to CPUSysState at
beginning, and it can be changed during VM exit/enter entry. There is no
function change, all is code movement or variable rename.

Hi,
The files in linux-user/loongarch64/* also need to be modified.
oops, loongarch-linux-user is missing here. Thanks for the reporting.
Will add and test this target.
Regards
Bibo Mao
Thanks.
