Chenghai Huang aaaa758294 crypto: hisilicon/qm - move the barrier before writing to the mailbox register 
[ Upstream commit ebf35d8f93 ]

Before sending the data via the mailbox to the hardware, to ensure
that the data accessed by the hardware is the most up-to-date,
a write barrier should be added before writing to the mailbox register.
The current memory barrier is placed after writing to the register,
the barrier order should be modified to be before writing to the register.

README 

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 reStructuredText 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.
