Michael Ellerman 8056fe28d0 powerpc/io: Add __raw_writeq_be() __raw_rm_writeq_be()
Add byte-swapping versions of __raw_writeq() and __raw_rm_writeq().

This allows us to avoid sparse warnings caused by passing __be64 to
__raw_writeq(), which takes unsigned long:

  arch/powerpc/platforms/powernv/pci-ioda.c:1981:38:
  warning: incorrect type in argument 1 (different base types)
      expected unsigned long [unsigned] v
      got restricted __be64 [usertype] <noident>

It's also generally preferable to use a byte-swapping accessor rather
than doing it by hand in the code, which is more bug prone.

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.
See Documentation/00-INDEX for a list of what is contained in each file.

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.
