8b640cc4c5 perf mem: Remove unused parameter from dump_raw_samples()
The 'evsel' parameter is not used, ditch it, reducing the function
signature.

f5fc14124c perf tools: Add data object to handle perf data file
This patch is adding 'struct perf_data_file' object as a placeholder for
all attributes regarding perf.data file handling. Changing
perf_session__new to take it as an argument.

The rest of the functionality will be added later to keep this change
simple enough, because all the places using perf_session are changed
now.

5c5e854bc7 perf tools: Add attr->mmap2 support
This patch adds support for the new PERF_RECORD_MMAP2 record type
exposed by the kernel. This is an extended PERF_RECORD_MMAP record.

It adds for each file-backed mapping the device major, minor number and
the inode number and generation.

This triplet uniquely identifies the source of a file-backed mapping. It
can be used to detect identical virtual mappings between processes, for
instance.

The patch will prefer MMAP2 over MMAP.

[ Cope with 314add6 "Change machine__findnew_thread() to set thread pid",
  fix 'perf test' regression test entry affected,
  use perf_missing_features.mmap2 to fallback to not using .mmap2 in older kernels,
  so that new tools can work with kernels where this feature is not present ]

ef89325f77 perf tools: Remove references to struct ip_event
The ip_event struct assumes fixed positions for ip, pid and tid.  That
is no longer true with the addition of PERF_SAMPLE_IDENTIFIER.  The
information is anyway in struct sample, so use that instead.

e44baa3ea1 perf tools: Remove filter parameter of perf_event__preprocess_sample()
Now that the symbol filter is recorded on the machine there is no need
to pass it to perf_event__preprocess_sample().  So remove it.
