Merge tag 'for_russell/arm-be-probes' of git://git.linaro.org/people/taras.kondratiuk...

It is reworked initial Ben's series for big endian support [1].
Dropped patches that are not directly related to probes and rebased
series on top of Dave Long's ARM uprobes series. Current set of
patches is enough to have functional BE kprobes and uprobes.

One ARM kprobe test fails on Cortex-A15 boards (TC2 and Keystone2 EVM),
while it passes on Pandaboard. The issue is not related to this series
and already present since v3.13-rc7.

v1..v2: Rebased series on top of Dave Long's ARM uprobes series.
        Now this series fixes both BE kprobes and BE uprobes.

Tested on Pandaboard ES and TI Keystone2 EVM.
