Pull perf fixes from Thomas Gleixner:
"A pile of perf updates:
Kernel side:
- Remove an incorrect warning in uprobe_init_insn() when
insn_get_length() fails. The error return code is handled at the
call site.
- Move the inline keyword to the right place in the perf ringbuffer
code to address a W=1 build warning.
Tooling:
perf stat:
- Fix metric column header display alignment
- Improve error messages for default attributes, providing better
output for error in command line.
- Add --interval-clear option, to provide a 'watch' like printing
perf script:
- Show hw-cache events too
perf c2c:
- Fix data dependency problem in layout of 'struct c2c_hist_entry'
Core:
- Do not blindly assume that 'struct perf_evsel' can be obtained via
a straight forward container_of() as there are call sites which
hand in a plain 'struct hist' which is not part of a container.
- Fix error index in the PMU event parser, so that error messages can
point to the problematic token"
* 'perf-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
perf/core: Move the inline keyword at the beginning of the function declaration
uprobes/x86: Remove incorrect WARN_ON() in uprobe_init_insn()
perf script: Show hw-cache events
perf c2c: Keep struct hist_entry at the end of struct c2c_hist_entry
perf stat: Add event parsing error handling to add_default_attributes
perf stat: Allow to specify specific metric column len
perf stat: Fix metric column header display alignment
perf stat: Use only color_fprintf call in print_metric_only

git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/urgent
Pull perf/urgent fixes and improvements from Arnaldo Carvalho de Melo:
perf stat:
- Fix metric column header display alignment (Jiri Olsa)
- Improve error messages for default attributes, providing better output
for error in command lines such as:
$ perf stat -T
Cannot set up transaction events
event syntax error: '..cycles,cpu/cycles-t/,cpu/tx-start/,cpu/el-start/,cpu/cycles-ct/}'
\___ unknown term
Where the "event syntax error" line now appears (Jiri Olsa)
- Add --interval-clear option, to provide a 'watch' like printing (Jiri Olsa)
perf script:
- Show hw-cache events too (Seeteena Thoufeek)
perf c2c:
- Fix data dependency problem in layout of 'struct c2c_hist_entry', where
its member 'struct hist_entry' must be at the end because it has a ZLA
as its last member, that gets space when handling callchains (Jiri Olsa)
Core:
- We cannot assume that a 'struct perf_evsel' is to be obtained from a
container_of operation on a 'struct hists' as there are tools, such as
'perf c2c' that uses 'struct hist' instances without having them in
container structs that also have 'struct perf_evsel' in a particular
layout, so provide a different way of figuring out if a 'struct hists'
and 'struct hist_entry' have callchains (Arnaldo Carvalho de Melo)
- Fix error index in the PMU event parser, so that error messages can
point to the problematic token (Jiri Olsa)

Exactly as the comment just before 'struct c2c_hist_entry" says, i.e.
the last entry in struct hist_entry is a zero length array, that when
allocating space for hist_entry gets extra space if callchains are in
use, which, if hist_entry is not at the end of c2c_hist_entry, the
members after it gets corrupted when callchains get added to the rb
trees collecting them, etc.

Add missing error handling for parse_events calls in add_default_attributes
functions. The error handler displays error details, like for transactions (-T):
Before:
$ perf stat -T
Cannot set up transaction events
After:
$ perf stat -T
Cannot set up transaction events
event syntax error: '..cycles,cpu/cycles-t/,cpu/tx-start/,cpu/el-start/,cpu/cycles-ct/}'

There are places where we have only access to struct hists and need to
know if any of its hist_entries has callchains, like when drawing
headers for the various output modes (stdio, TUI, etc), so, when adding
a new hist_entry, check if it has callchains, storing this info for
later use by hists__has_callchains().
This reimplementation is necessary because not always a 'struct hists'
is allocated together with a 'struct perf evsel', so we can't go from
'hists' to 'perf_event_attr.sample_type & PERF_SAMPLE_CALLCHAIN'.

Since we can't go from struct hists to struct evsel for all cases (c2c
is an exception) and we have access to the hist_entry, use
hist_entry__has_callchains() in the GTK+ hists browser to figure out
if callchains are available.

Since 'perf c2c' uses 'struct hists' not allocated together with a
'struct perf_evsel' instance, we can't go from a 'struct hist_entry'
pointer to a 'struct perf_evsel' via he->hists, so, instead, check if
space was set aside for hist_entry->callchain[0] at hist_entry__new()
time.

So that we can figure out the real size of the struct and also be able
to tell if callchains may be present in this histogram entry.
Since we can't always guarantee that from hist_entry->hists we can use
hists_to_evsel, to then look at evsel->attr.sample_type for
PERF_SAMPLE_CALLCHAIN, like with the 'perf c2c' tool, that uses plain
'struct hists' instances, we need another way of deciding if a specific
hist_entry instance has callchains associated with it, i.e. if its
hist_entry->callchain[0] has space allocated for.

- an errata workaround for the BCM5300X platform.
- a fix to ftrace function graph tracing, broken for a long time with
the fix applying cleanly back as far as v3.17.
- addition of read barriers to in{b,w,l,q}() functions, matching
behavior of other architectures & mirroring the equivalent addition
to read{b,w,l,q} in v4.17-rc2.

- Restartable sequences support is added, including MIPS support in

Implement support for both MIPS32 & MIPS64 in the rseq selftests, in
order to sanity check the recently enabled rseq syscall.
The tests all pass on a MIPS Boston development board running either a
MIPS32r2 interAptiv CPU & a MIPS64r6 I6500 CPU, both of which were
configured with 2 cores each of which have 2 hardware threads (VP(E)s) -
ie. 4 CPUs.

Change it to return kselftest skip code when a test gets skipped to
clearly report that the test could not be run. Add an explicit check
for module presence and return skip code if module isn't present.
Kselftest framework SKIP code is 4 and the framework prints appropriate
messages to indicate that the test is skipped.

Pull power management updates from Rafael Wysocki:
"These are mostly fixes, including some fixes for changes made during
the recent merge window and some "stable" material, plus some minor
extensions of the turbostat utility.
Specifics:
- Fix the PM core to avoid introducing a runtime PM usage counter
imbalance when adding device links during driver probe (Rafael
Wysocki).
- Fix the operating performance points (OPP) framework to ensure that
the regulator voltage is always updated as appropriate when
updating clock rates (Waldemar Rymarkiewicz).
- Fix the intel_pstate driver to use correct max/min limits for cores
with differing maximum frequences (Srinivas Pandruvada).
- Fix a typo in the intel_pstate driver documentation (Rafael
Wysocki).
- Fix two issues with the recently added Kryo cpufreq driver (Ilia
Lin).
- Fix two recent regressions and some other minor issues in the
turbostat utility and extend it to provide some more diagnostic
information (Len Brown, Nathan Ciobanu)"

Running turbostat on machines that don't expose nodes
in sysfs (no /sys/bus/node) causes a segfault or a -nan
value diesplayed in the log. This is caused by
physical_node_id being reported as -1 and logical_node_id
being calculated as a negative number resulting in the new
GET_THREAD/GET_CORE returning an incorrect address.

Daniel Borkmann says:
====================
pull-request: bpf 2018-06-16
The following pull-request contains BPF updates for your *net* tree.
The main changes are:
1) Fix a panic in devmap handling in generic XDP where return type
of __devmap_lookup_elem() got changed recently but generic XDP
code missed the related update, from Toshiaki.
2) Fix a freeze when BPF progs are loaded that include BPF to BPF
calls when JIT is enabled where we would later bail out via error
path w/o dropping kallsyms, and another one to silence syzkaller
splats from locking prog read-only, from Daniel.
3) Fix a bug in test_offloads.py BPF selftest which must not assume
that the underlying system have no BPF progs loaded prior to test,
and one in bpftool to fix accuracy of program load time, from Jakub.
4) Fix a bug in bpftool's probe for availability of the bpf(2)
BPF_TASK_FD_QUERY subcommand, from Yonghong.
5) Fix a regression in AF_XDP's XDP_SKB receive path where queue
id check got erroneously removed, from Björn.
6) Fix missing state cleanup in BPF's xfrm tunnel test, from William.
7) Check tunnel type more accurately in BPF's tunnel collect metadata
kselftest, from Jian.
8) Fix missing Kconfig fragments for BPF kselftests, from Anders.
