Received from Mark Salyzyn,
Take the expose_physicals flag and allow the user to select default (physicals
available via /dev/sg), exposed (physicals available via /dev/sd for
experimental reasons) and hidden (physicals blocked from all access). This
expands the functionality of the previous expose_physicals insmod parameter
which was added to support some experimental configurations.

The patch has been updated after talking with Mark about Christoph's
comments on the previous version of the patch.
