Subject: [PATCH AUTOSEL 5.10 01/16] dmaengine: idxd: depends on !UML

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

[ Upstream commit b2296eeac91555bd13f774efa7ab7d4b12fb71ef ]

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.
