Hi all,

I had to make a change to 3.0-RELEASE to get process size 
limit > 2GB to work:

In /usr/src/sys/kern/imgact_elf.c:

old:
     addr = 2L*MAXDSIZ; /* May depend on OS type XXX */

new:
     addr = (MAXDSIZ+(128<<20)); /* Fix for MAXDSIZ > 2GB */

With this change and these options:

options "MAXDSIZ=(3584UL*1024*1024)"
options "DFLDSIZ=(3584UL*1024*1024)"

I can now run a 3.5GB process on my SC450NX with 2 Xeon-400, 2GB DRAM
(though I've only run a simple test case so far, I haven't bashed
it hard).

Regards
     Richard Cownie
