Subject: dmaengine: ioat: depends on !UML
X-Git-Url: https://git.kernel.dk/?a=commitdiff_plain;h=9c1ea8537730790ee183fa32379932f777c95d17;p=linux-block.git

dmaengine: ioat: depends on !UML

[ 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.
