/*
*Security note:
* The hardware protection mechanism works like this: Each device object that
* is subject to UAR doorbells (QP/SQ/CQ) gets a UAR ID (called uar_page in
* the device specification manual) upon its creation. Then upon doorbell,
* hardware fetches the object context for which the doorbell was rang, and
* validates that the UAR through which the DB was rang matches the UAR ID
* of the object.
* If no match the doorbell is silently ignored by the hardware. Of course,
* the user cannot ring a doorbell on a UAR that was not mapped to it.
* Now in devx, as the devx kernel does not manipulate the QP/SQ/CQ command
* mailboxes (except tagging them with UID), we expose to the user its UAR
* ID, so it can embed it in these objects in the expected specification
* format. So the only thing the user can do is hurt itself by creating a
* QP/SQ/CQ with a UAR ID other than his, and then in this case other users
* may ring a doorbell on its objects.
* The consequence of that will be that another user can schedule a QP/SQ
* of the buggy user for execution (just insert it to the hardware schedule
* queue or arm its CQ for event generation), no further harm is expected.
