Subject: [PATCH] dmaengine: ioat: depends on !UML
Git-commit: bbac7a92a46f0876e588722ebe552ddfe6fd790f
Patch-mainline: v5.15-rc1
References: stable-5.14.8
[ 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.
