Mike Rapoport 2e76799725 microblaze: don't treat zero reserved memory regions as error 
[ Upstream commit 0075df288d ]

Before commit 721f4a6526 ("mm/memblock: remove empty dummy entry") the
check for non-zero of memblock.reserved.cnt in mmu_init() would always
be true either because  memblock.reserved.cnt is initialized to 1 or
because there were memory reservations earlier.

The removal of dummy empty entry in memblock caused this check to fail
because now memblock.reserved.cnt is initialized to 0.

Remove the check for non-zero of memblock.reserved.cnt because it's
perfectly fine to have an empty memblock.reserved array that early in
boot.

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.
