Weitao Wang 2a865a6522 xhci: Fix TRB prefetch issue of ZHAOXIN hosts 
On some ZHAOXIN hosts, xHCI will prefetch TRB for performance
improvement. However this TRB prefetch mechanism may cross page boundary,
which may access memory not allocated by xHCI driver. In order to fix
this issue, two pages was allocated for a segment and only the first
page will be used. And add a quirk XHCI_ZHAOXIN_TRB_FETCH for this issue.

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.
