commit 32a932332c8bad842804842eaf9651ad6268e637
Author: Ingo Molnar <mingo@elte.hu>
Date:   Wed Feb 6 22:39:44 2008 +0100

    brk randomization: introduce CONFIG_COMPAT_BRK
    
    based on similar patch from: Pavel Machek <pavel@ucw.cz>
    
    Introduce CONFIG_COMPAT_BRK. If disabled then the kernel is free
    (but not obliged to) randomize the brk area.
    
    Heap randomization breaks ancient binaries, so we keep COMPAT_BRK
    enabled by default.
