Subject: [PATCH 4.19 21/34] dmaengine: ioat: depends on !UML

From: Johannes Berg <johannes.berg@...el.com>

[ 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.
