[PATCH v2] Fix: buffer overflow during hvc_alloc().
From: Andrew Melnychenko <andrew at daynix.com>
If there is a lot(more then 16) of virtio-console devices
or virtio_console module is reloaded
- buffers 'vtermnos' and 'cons_ops' are overflowed.
In older kernels it overruns spinlock which leads to kernel freezing:
