These changes are the raw update to linux-4.4.6-rt14. Kernel sources

are taken from kernel.org, and rt patch from the rt wiki download page.

During the rebasing, the following patch collided:

Force tick interrupt and get rid of softirq magic(I70131fb85).

Collisions have been removed because its logic was found on the
source already.

- * Verbs Request Objects:
- *
- * VQ Request Objects are allocated by the kernel verbs handlers.
- * They contain a wait object, a refcnt, an atomic bool indicating that the
- * adapter has replied, and a copy of the verb reply work request.
- * A pointer to the VQ Request Object is passed down in the context
- * field of the work request message, and reflected back by the adapter
- * in the verbs reply message.  The function handle_vq() in the interrupt
- * path will use this pointer to:
- * 	1) append a copy of the verbs reply message
- * 	2) mark that the reply is ready
- * 	3) wake up the kernel verbs handler blocked awaiting the reply.
- *
- *
- * The kernel verbs handlers do a "get" to put a 2nd reference on the
- * VQ Request object.  If the kernel verbs handler exits before the adapter
- * can respond, this extra reference will keep the VQ Request object around
- * until the adapter's reply can be processed.  The reason we need this is
- * because a pointer to this object is stuffed into the context field of
- * the verbs work request message, and reflected back in the reply message.
- * It is used in the interrupt handler (handle_vq()) to wake up the appropriate
- * kernel verb handler that is blocked awaiting the verb reply.
- * So handle_vq() will do a "put" on the object when it's done accessing it.
- * NOTE:  If we guarantee that the kernel verb handler will never bail before
- *        getting the reply, then we don't need these refcnts.
- *
- *
- * VQ Request objects are freed by the kernel verbs handlers only
- * after the verb has been processed, or when the adapter fails and
- * does not reply.
- *
- *
- * Verbs Reply Buffers:
- *
- * VQ Reply bufs are local host memory copies of a
- * outstanding Verb Request reply
- * message.  The are always allocated by the kernel verbs handlers, and _may_ be
- * freed by either the kernel verbs handler -or- the interrupt handler.  The
- * kernel verbs handler _must_ free the repbuf, then free the vq request object
- * in that order.
