[PATCH] [natty/omap4] CVE-2011-2479

[Paolo Pisati]

CVE-2011-2479:
	It was found that an mmap() call with the MAP_PRIVATE flag on "/dev/zero"
	would create transparent hugepages and trigger a certain robustness check.
	A local, unprivileged user could use this flaw to cause a denial of service.

Cherry picked from natty/master.
