Subject: [PATCH v2 2/2] riscv: Use generic pgprot_* macros from <linux/pgtable.h>
Date: Wed, 15 Jul 2020 08:33:40 +0300
Message-ID: <20200715053340.576300-2-penberg@gmail.com> (raw)
In-Reply-To: <20200715053340.576300-1-penberg@gmail.com>

From: Pekka Enberg <penberg@kernel.org>

The <linux/pgtable.h> header now defines generic pgprot_ macros also for
the no-MMU configuration, so let's use them.
