mainlining shenanigans
0e801d547c
This series tries to reduce a whole bunch of overhead in each SPI transfer. Much of this overhead is new with the recent interconnect changes, but even without those changes we still had some overhead that we could avoid. Let's avoid all of it. These changes are atop the Qualcomm tree to avoid merge conflicts. If they look good, the most expedient way to land them is probably to get Ack's from Mark and land then via the Qualcomm tree. Most testing was done on the Chrome OS 5.4 tree, but sanity check was done on mainline.

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.
