Subject: [PATCH v3 07/17] mircoblaze: drop unneeded NUMA and sparsemem initializations
Date: Tue, 18 Aug 2020 18:16:24 +0300 [thread overview]
Message-ID: <20200818151634.14343-8-rppt@kernel.org> (raw)
In-Reply-To: <20200818151634.14343-1-rppt@kernel.org>
From: Mike Rapoport <rppt@linux•ibm.com>
microblaze does not support neither NUMA not SPARSMEM, so there is no point
to call memblock_set_node() and sparse_memory_present_with_active_regions()
functions during microblaze memory initialization.
Remove these calls and the surrounding code.
