perf/urgent fixes:
- Show group details on the title line in the annotate browser
and 'perf annotate --stdio2' output, so that the per-event
columns can have headers (Arnaldo Carvalho de Melo)
- Fixup vertical line separating metrics from instructions and
cleaning unused lines at the bottom, both in the annotate TUI
browser (Arnaldo Carvalho de Melo)
- Remove duplicated 'samples' in lost samples warning in
'perf report' (Arnaldo Carvalho de Melo)
- Synchronize i915_drm.h, silencing the perf build process,
automagically adding support for the new DRM_I915_QUERY
ioctl (Arnaldo Carvalho de Melo)
- Make auxtrace_queues__add_buffer() allocate struct buffer,
from a patchkit already applied (Adrian Hunter)

tools headers uapi: Synchronize i915_drm.h
To pick up the changes in:
c822e0591855 drm/i915: expose rcs topology through query uAPI
a446ae2c6e65 drm/i915: add query uAPI
This affects 'perf trace', that automagically gets the definition of the
new I915_QUERY DRM ioctl:

I.e. on systems where this is used it will appear when, for instance,
one does a system wide 'perf trace' session looking for ioctl calls,
just like it does with the previously implemented DRM_I915 ioctls:
# perf trace -e ioctl --filter-pids 2190
