Linux 2.4.17 bug, mmap of /dev/mem

[David Ashley]

I have been trying other kernels with some different results
2.4.17 = has mmap problem
2.4.14 = has mmap problem
2.4.13 = has mmap problem
2.4.12 = has mmap problem
2.4.10 = has mmap problem but takes more iterations to happen
2.4.8  = not quite done getting it to boot.

The only files I change to get a kernel to boot on our box are:
Makefile
  set arch to ppc and set the CROSS_COMPILE
arch/ppc/8260_io/fcc_enet.c
arch/ppc/8260_io/uart.c
arch/ppc/8260_io/commproc.c
  Slight changes to deal with our board's io port assignments
include/asm-ppc/est8260.c
  changes in the boardinfo structure passed from ppcboot
fs/proc/proc_misc.c
  added a /proc file to view some of the boardinfo structure

I'm not initializing usb or pci in the non-2.4.17 kernels.
