[Nicolas Pitre]

Russell, could you pull the following for the next merge window:

	git://git.linaro.org/nico/arm_security

This contains a few security features that are present on x86 and 
missing on ARM.  Those patches were posted on the list a while ago and 
no objections came back.

Nicolas Pitre (4):
      [ARM] implement arch_randomize_brk()
      [ARM] add address randomization to mmap()
      ARM: initial stack protector (-fstack-protector) support
      ARM: stack protector: change the canary value per task
