f30d460fa3 virtio-devices: seccomp: Move mprotect() to virtio common rules 
It's perfectly reasonable to expect if that some virtio threads trigger
libc behaviour that needs mprotect() that all virtio threads would do
the same.

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.

f4495de143 vmm: Improve handling of shared memory backing 
As huge pages are always MAP_SHARED then where the shared memory would

instead for huge pages.

The checking is also extended to cover the memory zones based

99d9a3d299 vmm: memory_manager: Avoid MAP_PRIVATE CoW with VFIO for hugepages too 
We can't use MAP_ANONYMOUS and still have huge pages so MAP_SHARED is
effectively required when using huge pages.

Unfortunately it is not as simple as always forcing MAP_SHARED if
hugepages is on as this might be inappropriate in the backing file case
hence why there is additional complexity of assigning to mmap_flags on
each case and the MAP_SHARED is only turned on for the anonymous file
huge page case as well as anonymous shared file case.

See: #4805
