VMCI queue pairs allow for bi-directional ordered communication between host and guests.

You should wrap your commit lines at 72 characters, like git asks you to :)

+/* Guest device port I/O. */
+struct PPNSet {
+	u64 num_produce_pages;
+	u64 num_consume_pages;
+	u32 *produce_ppns;
+	u32 *consume_ppns;
+	bool initialized;
+};

I know this is a private structure to the driver, so it's not that big
of a deal at all, but the naming for this is a bit odd (mixed case.)

Not a show stopper at all, but if you had run checkpatch.pl on it, it
would have warned you about this.
