Merge tag 'perf-core-for-mingo-3' 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:

User visible changes:

- Improve --filter support for 'perf probe', allowing using its arguments
on other commands, as --add, --del, etc (Masami Hiramatsu)

- Show warning when running 'perf kmem stat' on a unsuitable perf.data file,
i.e. one with events that are not the ones required for the stat variant
used (Namhyung Kim).

Infrastructure changes:

- Auxtrace support patches, paving the way to support Intel PT and BTS (Adrian Hunter)

- hists browser (top, report) refactorings (Namhyung Kim)

perf tools: Add parse_events_error interface

Adding support to return error information from parse_events function.
Following struct will be populated by parse_events function on return:

struct parse_events_error {
int idx;
char *str;
char *help;
};

where 'idx' is the position in the string where the parsing failed,
'str' contains dynamically allocated error string describing the error
and 'help' is optional help string.

The change contains reporting function, which currently does not display
anything. The code changes to supply error data for specific event types
are coming in next patches. However this is what the expected output is:

$ sudo perf record -e 'sched:krava' ls
event syntax error: 'sched:krava'
\___ unknown tracepoint
...

$ perf record -e 'cpu/even=0x1/' ls
event syntax error: 'cpu/even=0x1/'
\___ unknown term

valid terms: pc,any,inv,edge,cmask,event,in_tx,ldlat,umask,in_tx_cp,offcore_rsp,config,config1,config2,name,period,branch_type
...

$ perf record -e cycles,cache-mises ls
event syntax error: '..es,cache-mises'
\___ parser error
...

The output functions cut the beginning of the event string so the error
starts up to 10th character and cut the end of the string of it crosses
the terminal width.

Merge branch 'perf-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip

Pull perf updates from Ingo Molnar:
"Kernel side changes:

- AMD range breakpoints support:

Extend breakpoint tools and core to support address range through
perf event with initial backend support for AMD extended
breakpoints.

The syntax is:

perf record -e mem:addr/len:type

For example set write breakpoint from 0x1000 to 0x1200 (0x1000 + 512)

perf record -e mem:0x1000/512:w

- event throttling/rotating fixes

- various event group handling fixes, cleanups and general paranoia
code to be more robust against bugs in the future.

- kernel stack overhead fixes

User-visible tooling side changes:

- Show precise number of samples in at the end of a 'record' session,
if processing build ids, since we will then traverse the whole
perf.data file and see all the PERF_RECORD_SAMPLE records,
otherwise stop showing the previous off-base heuristicly counted
number of "samples" (Namhyung Kim).

- Support to read compressed module from build-id cache (Namhyung
Kim)

- Enable sampling loads and stores simultaneously in 'perf mem'
(Stephane Eranian)

- 'perf diff' output improvements (Namhyung Kim)

- Fix error reporting for evsel pgfault constructor (Arnaldo Carvalho
de Melo)

Tooling side infrastructure changes:

- Cache eh/debug frame offset for dwarf unwind (Namhyung Kim)

- Support parsing parameterized events (Cody P Schafer)

- Add support for IP address formats in libtraceevent (David Ahern)

Plus other misc fixes"

ASoC: Fixes for v3.19

There's a lot more fixes here than I'd like since I've been lax in
sending things throughout the release cycle but there's only two in
generic code and they've had quite some time to cook in -next so
hopefully on balance are OK.

The two generic fixes are a fix for crashes on capture DAIs in the
compress code and a fix for error handling on probe failures which would
have been harmless in the past but now oopses with the new dynamic probe
code.
