Subject: [PATCH AUTOSEL 5.5 31/41] riscv: Force flat memory model with no-mmu
Date: Sun, 15 Mar 2020 22:33:09 -0400	[thread overview]
Message-ID: <20200316023319.749-31-sashal@kernel.org> (raw)
In-Reply-To: <20200316023319.749-1-sashal@kernel.org>

From: Damien Le Moal <damien.lemoal@wdc.com>

[ Upstream commit aa2734202acc506d09c8e641db4da161f902df27 ]

Compilation errors trigger if ARCH_SPARSEMEM_ENABLE is enabled for
a nommu kernel. Since the sparsemem model does not make sense anyway
for the nommu case, do not allow selecting this option to always use
the flatmem model.
