With irq_entry already being associated with the wq in a 1:1 relationship, embed the irq_entry in the idxd_wq struct and remove back pointers for idxe_wq and idxd_device. In the process of this work, clean up the interrupt handle assignment so that there's no decision to be made during submit call on where interrupt handle value comes from. Set the interrupt handle during irq request initialization time. irq_entry 0 is designated as special and is tied to the device itself.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
