Subject: [PATCH v2 16/20] mm: remove early_pfn_in_nid() and CONFIG_NODES_SPAN_OTHER_NODES
Date: Wed, 29 Apr 2020 15:11:22 +0300 [thread overview]
Message-ID: <20200429121126.17989-17-rppt@kernel.org> (raw)
In-Reply-To: <20200429121126.17989-1-rppt@kernel.org>
From: Mike Rapoport <rppt@linux.ibm.com>
The commit f47ac088c406 ("mm: memmap_init: iterate over memblock regions
rather that check each PFN") made early_pfn_in_nid() obsolete and since
CONFIG_NODES_SPAN_OTHER_NODES is only used to pick a stub or a real
implementation of early_pfn_in_nid() it is also not needed anymore.
Remove both early_pfn_in_nid() and the CONFIG_NODES_SPAN_OTHER_NODES.
