Hi all, x86 currently has some quirks to force lower dma masks. They are mostly useful for certain VIA systems that otherwise corrupt data, but otherwise don't make much sense given that the modern DMA APIs do the right thing automatically.
This series dumps a few of these old kernel command lines (including their not really working version on ia64), and moves the VIA quirk to a flag in struct device so that it can be apply generically. This will be needed to support Xylinx root ports with a similar issue that show up in common RISC-V boards.
