VM/Security: add security hook to do_brk (CVE-2007-6434)
patch ecaf18c15aac8bb9bed7b7aa0e382fe252e275d5 in mainline.
VM/Security: add security hook to do_brk
Given a specifically crafted binary do_brk() can be used to get low pages
available in userspace virtual memory and can thus be used to circumvent
the mmap_min_addr low memory protection. Add security checks in do_brk().
