Chop vlv_sprite_update() into two halves. Fist half becomes the _noarm() variant, second part the _arm() variant. Fortunately I have already previously grouped the register writes into roughtly the correct order, so the split looks surprisingly clean. Looks like most of the hardware logic was copied from the pre-ctg sprite C, so SPSTRIDE/POS/SIZE are armed by SPSURF, while the rest are self arming. SPCONSTALPHA is the one entirely new register that didn't exist in the old sprite C, and looks like that one is self arming. The CHV pipe B CSC is also self arming, like the rest of the CHV pipe B additions. I didn't have time to capture i915_update_info numbers for these, but since all the other platforms generally showed improvements, and crucially no regression, I am fairly confident this should behave similarly.

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.
