Revert "tools lib lk: Fix for cross build" (2013-08-07 17:35:41 -0300)
----------------------------------------------------------------
perf/core improvements and fixes:
. Do annotation using /proc/kcore and /proc/kallsyms, removing the
need for a vmlinux file kernel assembly annotation. This also improves
this use case because vmlinux has just the initial kernel image, not
what is actually in use after various code patchings by things like
alternatives, etc. From Adrian Hunter.
. Various improvements and fixes to the "vmlinux matches kallsyms" 'perf test'
entry, related to the /proc/kcore annotation feature.
. Add --initial-delay option to 'perf stat' to skip measuring for
the startup phase, from Andi Kleen.
. perf kvm stat live mode, that combines aspects of 'perf kvm stat' record and
report, from David Ahern.
. Add option to analyze specific VM in perf kvm stat report, from David Ahern.
. Do not require /lib/modules/* on a guest, fix from Jason Wessel.
. Group leader sampling, that allows just one event in a group to sample while
the other events have just its values read, from Jiri Olsa.
. Add support for a new modifier "D", which requests that the event, or group
of events, be pinned to the PMU, from Michael Ellerman.
. Fix segmentation fault on the gtk browser, from Namhyung Kim.
