Jonathan Cameron 7b09fa7ea4 mm/memory_hotplug: drop memblock_phys_free() call in try_remove_memory() 
The call for memblock_phys_free() in try_remove_memory() does not balance
any call to memblock_alloc() (or memblock_reserve() for that matter).

There are no memblock_reserve() calls in mm/memory_hotplug.c, no memblock
allocations possible after mm_core_init(), and even if memblock_add_node()
called from add_memory_resource() would need to allocate memory, that
memory would ba allocated from slab.

The patch f9126ab924 ("memory-hotplug: fix wrong edge when hot add a new
node") that introduced that call to memblock_free() does not provide
adequate description why that was required and tinkering with memblock in
the context of memory hotplug on x86 seems bogus because x86 never kept
memblock after boot anyway.

Drop memblock_phys_free() call in try_remove_memory().

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.
