From: Arnd Bergmann <arnd@xxxxxxxx> The virt_to_bus/bus_to_virt interface has been deprecated for decades. After Jakub Kicinski put a lot of work into cleaning out the network drivers using them, there are only a couple of other drivers left, which can all be removed or otherwise cleaned up, to remove the old interface for good. Any out of tree drivers using virt_to_bus() should be converted to using the dma-mapping interfaces, typically dma_alloc_coherent() or dma_map_single()). There are a few m68k and ppc32 specific drivers that keep using the interfaces, but these are all guarded with architecture-specific Kconfig dependencies, and are not actually broken. There are still a number of drivers that are using virt_to_phys() and phys_to_virt() in place of dma-mapping operations, and these are often broken, but they are out of scope for this series.
I'll take patches 1 and 2 right now through my staging tree if that's ok. thanks, greg k-h
