Subject: [PATCH v2 1/4] x86/mm: Export force_dma_unencrypted
Date: Tue,  3 Sep 2019 15:15:01 +0200	[thread overview]
Message-ID: <20190903131504.18935-2-thomas_os@shipmail.org> (raw)
In-Reply-To: <20190903131504.18935-1-thomas_os@shipmail.org>

From: Thomas Hellstrom <thellstrom@vmware.com>

The force_dma_unencrypted symbol is needed by TTM to set up the correct
page protection when memory encryption is active. Export it.
