When we hotplug vcpus, cpu_update_state is added to vm_change_state_head
in kvm_arch_init_vcpu(). But it forgot to delete in kvm_arch_destroy_vcpu()
after

kvm_arch_destroy_vcpu() to fix that.

Hello Daniel,
Ok, TigerVNC, added -shared=1 to behave the same

The COR-filter driver should support a redirecting function to refresh
filenames. Otherwise, a file name of the filter will be copied
instead of the one of a data node. It is also true for the function

We have a test suite that relies on _apksigner_ working. It was running

Adjust some of the aarch64 code to look at the reginfo struct
instead of looking at test_sve, so that we do not need to pass
the --test-sve option in order to dump sve trace files.

In 1dc8425e551, while converting to gvec, I added an extra range check
against the shift count. This was unnecessary because the encoding of
the shift count produces 0 to the element size - 1.

This patch set does alter the format of the trace files, and thus

In addition, the new --dump option allows one to inspect the
