8e3b351038 arch: x86_64: Use host cpuid information for L2 cache for older KVM 
If the KVM version is too old (pre Linux 5.7) then fetch the CPUID
information from the host and use that in the guest. We prefer the KVM
version over the host version as that would use the CPUID for the
running CPU vs the CPU that runs this code which might be different due
to a hybrid topology.

Fixes: #4918

57508a4b1c virtio-net: net: Wait for threads to exit on Drop 
It is required to close all file descriptors pointing to an opened TAP
device prior to reopening the TAP device; otherwise it will return
-EBUSY as the device can only be opened once (excluding MQ use cases.)

When rebooting the VM the virtio-net threads would still be running and
so the TAP file descriptor may not have been closed. To ensure that the
TAP FD is closed wait for all the epoll threads to exit after receiving the
KILL_EVENT.
