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
