David Howells bdb7de7ed5 iov_iter, x86: Be consistent about the __user tag on copy_mc_to_user() 
[ Upstream commit 066baf92bed934c9fb4bcee97a193f47aa63431c ]

copy_mc_to_user() has the destination marked __user on powerpc, but not on
x86; the latter results in a sparse warning in lib/iov_iter.c.

Fix this by applying the tag on x86 too.

Fixes: ec6347bb43 ("x86, powerpc: Rename memcpy_mcsafe() to copy_mc_to_{user, kernel}()")

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 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.
