From: James Simmons <jsimmons@acsu.buffalo.edu>
It was bothering me so much about the discussion we had about
rvmalloc I made a patch for it. This patch places the code inside
vmalloc.c and I changed vmalloc.h so drivers can use rvmalloc,
rvfree, kvirt_to_bus, and kvirt_to_pa. I removed the duplicated
code out of bttv.c and the USB drivers using it. I don't know if my
solution is correct but its a start. Modify it at will. It's
against 2.3.43-8 and it compiles but I couldn't test it. I don't
have any drivers that use this code. So please test it as well.
Please use the new portable pci_{map,unmap}_*() interfaces or
your code will not work on Alpha and Sparc PCI systems. (hint:
Add a "pci_dev *" argument to your publicly exported entry points)
In fact on Sparc, virt_to_bus() no longer exists and therefore
the kernel won't even build if you try to reference it. (we don't
support any ISA devices on Sparc64, so this is OK)
