Hi,

Now that this series is in master, could it also be considered for
stable-11.1?

Both commits are needed together:

7df9aa5 target/riscv/kvm: Synchronize privilege mode
ddac7cf target/riscv/kvm: Preserve MP state across migration

They fix RISC-V KVM live migration with multiple vCPUs. Without the
second fix, secondary vCPUs can remain stopped after migration; without
the first, the vCPU privilege mode may be restored incorrectly.

I tested the series on native riscv64 hardware with KVM enabled,
including multi-vCPU live migration, a 24-hour post-migration run, and
multiple repeated migrations across two guests. I did not observe guest
hangs or soft lockups.

Thanks,
Xie Bo
