Subject: [PATCH v2 07/17] mircoblaze: drop unneeded NUMA and sparsemem initializations
Date: Sun, 2 Aug 2020 19:35:51 +0300 [thread overview]
Message-ID: <20200802163601.8189-8-rppt@kernel.org> (raw)
In-Reply-To: <20200802163601.8189-1-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.
