Linus Torvalds b59eea554f vfs: fix flock compat thinko 
Michael Ellerman reported that commit 8c6657cb50 ("Switch flock
copyin/copyout primitives to copy_{from,to}_user()") broke his
networking on a bunch of PPC machines (64-bit kernel, 32-bit userspace).

The reason is a brown-paper bug by that commit, which had the arguments
to "copy_flock_fields()" in the wrong order, breaking the compat
handling for file locking.  Apparently very few people run 32-bit user
space on x86 any more, so the PPC people got the honor of noticing this
"feature".

Michael also sent a minimal diff that just changed the order of the
arguments in that macro.

This is not that minimal diff.

This not only changes the order of the arguments in the macro, it also
changes them to be pointers (to be consistent with all the other uses of
those pointers), and makes the functions that do all of this also have
the proper "const" attribution on the source pointers in order to make
issues like that (using the source as a destination) be really obvious.

README 

Linux kernel
============

This file was moved to Documentation/admin-guide/README.rst

Please notice that there are several guides for kernel developers and users.
These guides can be rendered in a number of formats, like HTML and PDF.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.

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.
