Forest Crossman 209b3ff98d usb: xhci: Fix ASMedia ASM1042A and ASM3242 DMA addressing
commit b71c669ad8 upstream.

I've confirmed that both the ASMedia ASM1042A and ASM3242 have the same
problem as the ASM1142 and ASM2142/ASM3142, where they lose some of the
upper bits of 64-bit DMA addresses. As with the other chips, this can
cause problems on systems where the upper bits matter, and adding the
XHCI_NO_64BIT_SUPPORT quirk completely fixes the 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.
