Description of problem:
HIGHMEM with real page (i.e. having memory over 896MB)
    cause several problems
    such as boot crash, vmalloc32 failure, etc.
No error when limit memory with boot command line option MEM=896M.


Version-Release number of selected component (if applicable):
kenel 2.4.20-13.9

How reproducible:
Always

Steps to Reproduce:
1. install kernel(kernel-2.4.20-13.9.athlon.rpm or
kernel-smp-2.4.20-13.9.athlon.rpm) on a machine with over 896MB memory.
2. boot
3. kernel panic

Note. sometimes, on some condition, boot will work.
    but when you continue to work on that machine, something funny with memory
allocation(such as vmalloc32) would occur.


Actual Results:  (1) kernel panic
    see screen shot attached


(2) vmalloc32 fail if luckily success to boot.


Expected Results:  Boot fine, work fine.
