Subject: [PATCH 4.4 14/28] iommu/amd: Finish TLB flush in amd_iommu_unmap()
Date: Mon, 16 Oct 2017 18:12:07 +0200 [thread overview]
Message-ID: <20171016160924.283890966@linuxfoundation.org> (raw)
In-Reply-To: <20171016160923.478701091@linuxfoundation.org>
4.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Joerg Roedel <jroedel@suse.de>
commit ce76353f169a6471542d999baf3d29b121dce9c0 upstream.
The function only sends the flush command to the IOMMU(s),
but does not wait for its completion when it returns. Fix
that.
Fixes: 601367d76bd1 ('x86/amd-iommu: Remove iommu_flush_domain function')
