[PATCH AUTOSEL 4.4 1/8] dmaengine: ioat: depends on !UML

From: Sasha Levin
Date: Mon Sep 13 2021 - 18:41:22 EST


From: Johannes Berg <johannes.berg@xxxxxxxxx>

[ Upstream commit bbac7a92a46f0876e588722ebe552ddfe6fd790f ]

Now that UML has PCI support, this driver must depend also on
!UML since it pokes at X86_64 architecture internals that don't
exist on ARCH=um.
