Subject: [PATCH v3 15/17] memblock: remove unused memblock_mem_size()
Date: Tue, 18 Aug 2020 18:16:32 +0300 [thread overview]
Message-ID: <20200818151634.14343-16-rppt@kernel.org> (raw)
In-Reply-To: <20200818151634.14343-1-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.
