Please note that there's no need for such patch. Instead of modifying the
kernel to tell "bigphysarea=40M" just boot with "mem=24M" and use
proper sw (no patch needed).
I wrote an "allocator.[ch]" staff (also compilable as standalone module)
to manage such high-memory buffers. It's in my drivers, at ftp.systemy.it/pub/develop (pxdrv*, pxc*, adl*).
