Liu Shixin f9e60becee cgroup/cpuset: use hotplug_memory_notifier() directly 
Patch series "mm: Use hotplug_memory_notifier() instead of
register_hotmemory_notifier()", v4.

Commit f02c696800 ("include/linux/memory.h: implement
register_hotmemory_notifier()") introduced register_hotmemory_notifier()
to avoid a compile problem with gcc-4.4.4:

    When CONFIG_MEMORY_HOTPLUG=n, we don't want the memory-hotplug notifier
    handlers to be included in the .o files, for space reasons.
    
    The existing hotplug_memory_notifier() tries to handle this but testing
    with gcc-4.4.4 shows that it doesn't work - the hotplug functions are
    still present in the .o files.

Since commit 76ae847497 ("Documentation: raise minimum supported
version of GCC to 5.1") has already updated the minimum gcc version to
5.1.  The previous problem mentioned in f02c696800 does not exist.  So
we can now revert to use hotplug_memory_notifier() directly rather than
register_hotmemory_notifier().

In the last patch, we move all hotplug memory notifier priority to same
file for easy sorting.


This patch (of 8):

Commit 76ae847497 ("Documentation: raise minimum supported version of
GCC to 5.1") updated the minimum gcc version to 5.1.  So the problem
mentioned in f02c696800 ("include/linux/memory.h: implement
register_hotmemory_notifier()") no longer exist.  So we can now switch to
use hotplug_memory_notifier() directly rather than
register_hotmemory_notifier().

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.
