Module Name:    src
Committed By:   elad
Date:           Fri Dec 28 17:14:51 UTC 2007

Modified Files:
        src/sys/kern: exec_elf32.c kern_exec.c kern_pax.c
        src/sys/sys: exec.h

Log Message:
Provide 8 more bits of stack randomization, from the PaX author.

While here, don't make too much use of one random value, and call
arc4random() directly. Allows for the removal of 'ep_random' from the
exec_package.
