[...] We have been using the bigphysarea patch and seems
to do what we need for this card. We have been using it sice the beginning to the 2.4 series kernel. My question is, is this patch still nessessary or is there possibly a way do do this now without the patch?
I think Pauline never bothered to submit it. In Welsh's times it was considered too esoteric for inclusion, but nowdays we carry so much bloat that I'd think bigphysarea can be included. If you want it included, take over the issue and bug Linus.

You can achieve the same thing without the bigphys patch. I was using the bigphys patch in the Dolphin SCI drivers, but with these systems having all this memory these days, just the standard get pages calls work well enough. To see an alternate implementation of bigphys that does not rely on big phys, look at memalloc.c in the SCI code base at
www.kernel.org/pub/linux/kernel/people/jmerkey/
and download the latest SCI drivers for Linux. I used to use the bigphys patch, but found it really wasn't necessary to do what I needed to do.
