This patch series adds support for locking guest memory to the bhyve
driver using the following elements
<memoryBacking>
<locked/>
</memoryBacking>
When specified, the -S flag is passed to the bhyve binary.

Thanks for the patches, I've pushed the series with some syntax-check
fixes (trailing whitespaces, tabs instead of whitespaces) and added
'Signed-off-by' line which is mandatory now.

Thanks for the patches, I've pushed the series with some syntax-check
fixes (trailing whitespaces, tabs instead of whitespaces) and added
'Signed-off-by' line which is mandatory now.
Note that 'Signed-off-by' should _NOT_ be added without explicit consent
of the author of the patches. Otherwise it defeats the purpose of
certification that the author agrees and complies with the Developer
certificate of origin. Adding it without explicit consent makes the
Signed-off-by line just a useless piece of jewelery added to appease the
push hook.

Oh, sorry about that. I assumed as Fabian is a long time contributor,
he's familiar with the general project policies.
Fabian, do you have any issue with that?
