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 would like the first two patches to either get merged through
the SCSI tree, or get an Ack from the SCSI maintainers so I can
merge them through the asm-generic tree

Changes since v1:
- dropped VME patches that are already in staging-next
- dropped media patch that gets merged independently
- added a networking patch and dropped it again after it got merged
- replace BusLogic removal with a workaround
