Why would we need that other symbol? Maxime

Why would we need > that other symbol? We don't. I wasn't aware that 6fc3a8636a7b exists and had this one in my tree prior to 6.0. (well... technically we do need those other symbols and don't need VIRTIO, but since CONFIG_UML_PCI_OVER_VIRTIO pull in those two, it also works). Since docs were not updated, I didn't see any conflicts when rebasing. Sorry for the noise, please ignore this patch. -Michał > > Maxime

I mean, the doc still isn't up to date, so please send that part of the patch :) Maxime

DRM depends on IOMEM and DMA, introduce an additional Kconfig to pull in IOMEM and DMA emulation on UML. Since --kconfig_add usage is no longer needed, remove it from documentation.
