Subject: [GIT PULL] IOMMU fixes for -rc6
Date: Fri, 27 Nov 2020 11:45:29 +0000	[thread overview]
Message-ID: <20201127114529.GB20418@willie-the-truck> (raw)

Hi again, Linus,

Here's another round of IOMMU fixes for -rc6 consisting mainly of a
bunch of independent driver fixes. Thomas agreed for me to take the
x86 'tboot' fix here, as it fixes a regression introduced by a vt-d
change.

Please pull,

Will
