Merge branch 'perf-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
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
perf stat: Add --interval-clear option
perf tools: Fix error index for pmu event parser
perf hists: Reimplement hists__has_callchains()
perf hists browser gtk: Use hist_entry__has_callchains()
perf hists: Make hist_entry__has_callchains() work with 'perf c2c'
perf hists: Save the callchain_size in struct hist_entry
