The vmalloc_start patches don't affect this problem at all. The results
are identical in all of the cases:

- VMALLOC_START at 0xfe600000
- VMALLOC_START reset to 0xfe300000
- VMALLOC_START set to vmalloc_start_addr (which gets set to 0xfe300000
on sun4m, and 0xfe600000 on sun4/sun4c) as in the patch I sent to the
list today.
