Subject: [PATCH] ARC: Use max_high_pfn as a HIGHMEM zone border
Date: Mon, 26 Apr 2021 13:10:04 +0300	[thread overview]
Message-ID: <20210426101004.42695-1-isaev@synopsys.com> (raw)

Commit 4af22ded0ecf ("arc: fix memory initialization for systems with two
memory banks") fixed highmem, but not for PAE case when highmem is
actually bigger than lowmem.
