Git pull request: ARM kprobes fixes

[Nicolas Pitre]

Russell, could you please pull the following:

	git://git.linaro.org/people/nico/linux kprobes

This is the comprehensive patch series from Jon Medhurst aka Tixy fixing 
various issues with the kprobes emulation code, plus one fix from Viktor 
Rosendahl.  This is based on v2.6.39-rc2 so not to conflict with the 
first of Viktor's patches already in mainline.  All those patches were 
posted on LAK and reviewed by me.

Obviously, this is not a small set of patches.  They are all fixes and 
pretty well isolated as shown by the diffstat though.  Up to you to push 
that to Linus during this -rc period, or wait for the next merge window.  
People aren't typically installing probes on the problematic 
instructions it seems, so this is probably not a matter of urgency.
