about a year ago there were some patches to move rvmalloc() into
vmalloc() as a blessed feature of the kernel. But it looks to
me like these patches didn't "take".

I note that at least 5 device drivers have similar implementations
of rvmalloc()/rvfree() et al:
ieee1394/video1394.c
usb/ibmcam.c
usb/ov511.c
media/video/bttv-driver.c
media/video/cpia.c
rvmalloc()/rvfree() are functions that are used to allocate large
amounts of physically non-contiguous kernel virtual memory that will
then be mmap()'ed into a user process.
I just got done writing a driver that needed rvmalloc() in order to do
chip level simulation. Yank and put to the rescue.
