perf powerpc: Fix build-test failure (2016-09-08 13:44:07 -0300)
----------------------------------------------------------------
perf/core improvements and fixes:
User visible:
- Add branch stack / basic block info to 'perf annotate --stdio', where for
each branch, we add an asm comment after the instruction with information on
how often it was taken and predicted. See example with color output at:
http://vger.kernel.org/~acme/perf/annotate_basic_blocks.png
(Peter Zijlstra)
- Only open an evsel in CPUs in its cpu map, fixing some use cases in
systems with multiple PMUs with different CPU maps (Mark Rutland)
- Fix handling of huge TLB maps, recognizing it as anonymous (Wang Nan)
Infrastructure:
- Remove the symbol filtering code, i.e. the callbacks passed to all functions
that could end up loading a DSO symtab, simplifying the code, eventually
allowing what we should have had since day one: removing the 'map' parameter
from dso__load() functions (Arnaldo Carvalho de Melo)
Arch specific build fixes:
- Fix detached tarball build on powerpc, where we were still accessing a
file outside tools/ (Ravi Bangoria)
Signed-off-by: Arnaldo Carvalho de Melo <acme@...hat.com>
----------------------------------------------------------------
Arnaldo Carvalho de Melo (5):
perf symbols: Mark if a symbol is idle in the library
perf top: Remove old kernel-only symbol filter
perf machine: Remove machine->symbol_filter and friends
perf test vmlinux: Remove dead symbol_filter_t code
perf symbols: Remove symbol_filter_t machinery
Mark Rutland (2):

perf pmu: Support alternative sysfs cpumask
Peter Zijlstra (1):
perf annotate: Add branch stack / basic block
Ravi Bangoria (1):
