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.

commit 09f736aa upstream. Turns out some xHC controllers require all 64 bits in the CRCR register to be written to execute a command abort. The lower 32 bits containing the command abort bit is written first. In case the command ring stops before we write the upper 32 bits then hardware may use these upper bits to set the commnd ring dequeue pointer. Solve this by making sure the upper 32 bits contain a valid command ring dequeue pointer. The original patch that only wrote the first 32 to stop the ring went to stable, so this fix should go there as well. Fixes: ff0e50d3 ("xhci: Fix command ring pointer corruption while aborting a command") Cc: stable@vger.kernel.org Tested-by:Pavankumar Kondeti <quic_pkondeti@quicinc.com> Signed-off-by:
