[PATCH 0/2] add perf-probe support on ARM

Perf-probe uses the KProbe events tracer to place and monitor probes
on the running Kernel.

This patch series adds both Kernel and tool support for this feature
on ARM.

Patches based on 2.6.35-rc3 [although perf record is currently broken
on all architectures for probe tracepoints. These patches also apply
cleanly to -tip/master where perf record works properly.]
