Merge tag 'perf-core-for-mingo' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/core Pull perf/core improvements and fixes from Arnaldo Carvalho de Melo: * Don't show scripts menu for 'perf top', fix from Feng Tang * Add framework for automated perf_event_attr tests, where tools with different command line options will be run from a 'perf test', via python glue, and the perf syscall will be intercepted to verify that the perf_event_attr fields set by the tool are those expected, from Jiri Olsa * Use normalized arch name for searching objdump path. This fixes cases where the system's objdump (e.g. x86_64) supports the architecture in the perf.data file (e.g. i686), but is not the same, fix from Namhyung Kim. * Postpone objdump check until annotation requested, from Namhyung Kim. * Add a 'link' method for hists, so that we can have the leader with buckets for all the entries in all the hists. This new method is now used in the default 'diff' output, making the sum of the 'baseline' column be 100%, eliminating blind spots. Now we need to use this for 'diff' with > 2 perf.data files and for multi event 'report' and 'annotate'. * libtraceevent fixes for compiler warnings trying to make perf it build on some distros, like fedora 14, 32-bit, some of the warnings really pointed to real bugs. * Remove temp dir on failure in 'perf test', fix from Jiri Olsa. * Fixes for handling data, stack mmaps, from Namhyung Kim. * Fix live annotation bug related to recent objdump lookup patches, from Namhyung Kim * Don't try to follow jump target on PLT symbols in the annotation browser, fix from Namhyung Kim. * Fix leak on hist_entry delete, from Namhyung Kim. * Fix a CPU_ALLOC related build error on builtin-test, from Zheng Liu.

The perf annotate browser on TUI can identify a jump target for a selected instruction. It assumes that the jump target is within the function but it's not the case of PLT symbols which have offset out of the function as a target. Since it caused a segmentation fault, do not try to follow jump target on the PLT symbols.

That given two hists will find the hist_entries (buckets) in the second hists that are for the same bucket in the first and link them, then it will look for all buckets in the second that don't have a counterpart in the first and will create a dummy counterpart that will then be linked to the entry in the second. For multiple events this will be done pairing the leader with all the other events in the group, so that in the end the leader will have all the buckets in all the hists in a group, dummy or not while the other hists will be left untouched.

We want to match more than two hists, so that we can match more than two perf.data files and moreover, match hist_entries (buckets) in multiple events in a group. So the "baseline"/"leader" will instead of a ->pair pointer, use a list_head, that will link to the pairs and hists__match use it. Following that perf_evlist__link will link the hists in its evsel groups.

Arnaldo reported that annotation during perf top resulted in a segfault. It was because the env->arch was NULL and we don't set it for a live session.

Since we allow multiple values in event field assignment, there's no need for 'optional' field.. old version removal leftover. Adding some comments into attr.py script regarding the test event load.

David reported that current perf report refused to run on a data file captured from a different machine because of objdump. Since the objdump tools won't be used unless annotation was requested, checking its presence at init time doesn't make sense.

Currently various hist browser functions receive 3 arguments for refreshing histogram but only used from a few places. Also it's only for perf top command so that it can be NULL for other (and probably most) cases. Pack them into a struct in order to reduce number of those unused arguments. This is a mechanical change and does not intend a functional change.

David reported that perf report for i686 target data on x86_64 host failed to work because it tried to find out cross-compiled objdump. However objdump for x86_64 is compatible to i686 so that it doesn't need to do it at all. To prevent similar artifacts, normalize arch name when comparing host and file architectures.
