Subject: [PATCH v2 15/17] memblock: remove unused memblock_mem_size()
Date: Sun,  2 Aug 2020 19:35:59 +0300
Message-ID: <20200802163601.8189-16-rppt@kernel.org> (raw)
In-Reply-To: <20200802163601.8189-1-rppt@kernel.org>

From: Mike Rapoport <rppt@linux.ibm.com>

The only user of memblock_mem_size() was x86 setup code, it is gone now and
memblock_mem_size() funciton can be removed.
