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"
