Tetsuo Handa dd2a5b5514 mm/util: make memdup_user_nul() similar to memdup_user() 
Since the string data to copy from userspace is likely less than PAGE_SIZE
bytes, replace GFP_KERNEL with GFP_USER like commit 6c2c97a24f
("memdup_user(): switch to GFP_USER") does and add __GFP_NOWARN like
commit 6c8fcc096b ("mm: don't let userspace spam allocations warnings")
does.  Also, use dedicated slab buckets like commit d73778e4b8
("mm/util: Use dedicated slab buckets for memdup_user()") does.

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.
