This patchset is heavily based on Sandeepa Prabhu's ARM v8 kprobes patches,
first seen in October 2013. This version attempts to address concerns raised by
reviewers and also fixes problems discovered during testing.

This patchset adds support for kernel probes(kprobes), jump probes(jprobes)
and return probes(kretprobes) support for ARM64.

The kprobes mechanism makes use of software breakpoint and single stepping
support available in the ARM v8 kernel.

This patch depends on:
[PATCH 1/2] Move the pt_regs_offset struct definition from arch to common include file
[PATCH 2/2] Consolidate redundant register/stack access code

Are these two queued somewhere? This series doesn't even build without


I posted the last revision of that on July 27. I don't know if they're "queued" somewhere. They do affect multiple architectures so I'm not certain where they would get queued. They also live in a branch in my own Linaro repo.

Was there a better way for me to deal with this dependency? I was reluctant to make this into one patch set as the other patch really does stand alone as a useful fix.
