Subject[patch 0/4] perf_counter tools: support annotation of live kernel modules
From
Date
Per $subject, this patch set only supports for the LIVE kernel.  It adds
support infrastructure for path discovery, load address lookup, and
symbol generation of live kernel modules.

TODO includes resurrection of live annotation in perf top, and support
for annotation and report generation of other than live modules. As the
patch set sits, Perf top can generate symbols from live binaries, but
there's no live annotation capability yet.

patch1: perf_counter tools: Make symbol loading consistently return number of loaded symbols.
patch2: perf_counter tools: Add infrastructure to support loading of kernel module symbols
patch3: perf_counter tools: connect module support infrastructure to symbol loading infrastructure
patch4: perf_counter tools: Enable kernel module symbol loading in tools

Comments and suggestions most welcome.

-Mike
