Pull perf fixes from Ingo Molnar:
"This tree contains various perf fixes on the kernel side, plus three
hw/event-enablement late additions:
- Intel Memory Bandwidth Monitoring events and handling
- the AMD Accumulated Power Mechanism reporting facility
- more IOMMU events
... and a final round of perf tooling updates/fixes"
* 'perf-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (44 commits)
perf llvm: Use strerror_r instead of the thread unsafe strerror one
perf llvm: Use realpath to canonicalize paths
perf tools: Unexport some methods unused outside strbuf.c
perf probe: No need to use formatting strbuf method
perf help: Use asprintf instead of adhoc equivalents
perf tools: Remove unused perf_pathdup, xstrdup functions
perf tools: Do not include stringify.h from the kernel sources
tools include: Copy linux/stringify.h from the kernel
tools lib traceevent: Remove redundant CPU output
perf tools: Remove needless 'extern' from function prototypes
perf tools: Simplify die() mechanism
perf tools: Remove unused DIE_IF macro
perf script: Remove lots of unused arguments
perf thread: Rename perf_event__preprocess_sample_addr to thread__resolve
perf machine: Rename perf_event__preprocess_sample to machine__resolve
perf tools: Add cpumode to struct perf_sample
perf tests: Forward the perf_sample in the dwarf unwind test
perf tools: Remove misplaced __maybe_unused
perf list: Fix documentation of :ppp
perf bench numa: Fix assertion for nodes bitfield
...
Pull perf/core improvements and fixes:
User visible fixes:
- Fix documentation of :ppp modifier in 'perf list' (Andi Kleen)
- Fix silly nodes bitfield bits/bytes length assertion in 'perf bench numa' (Jakub Jelen)
- Remove redundant CPU output in libtraceevent (Steven Rostedt)
- Remove 'core_id' check in topology 'perf test' (Sukadev Bhattiprolu)
Infrastructure changes/fixes:
- Record text offset in dso to calculate objdump address, to use with
modules in addition to vDSO symbol address calculations (Wang Nan)
- Move utilities.mak from perf to tools/scripts/ (Arnaldo Carvalho de Melo)
- Add cpumode to the perf_sample struct, this way we don't need to pass
the union event to the machine and thread resolving routines, shortening
function signatures and allowing the future introduction of a way
to use tracepoint events instead of the unavailable HW cycles counter on
powerpc guests in perf kvm by just hooking on perf_evsel__parse_sample,
at the end (Arnaldo Carvalho de Melo)
- Remove/unexport die() related infrastructure, that at some point will
finally be removed (Arnaldo Carvalho de Melo)
- Adopt linux/stringify.h from the kernel sources, not to touch this
kernel header from tools/ (Arnaldo Carvalho de Melo)
- Stop using strbuf for things we can instead trivially use libc's asprintf()
(Arnaldo Carvalho de Melo)
- Ditch tools/lib/util/abspath.c, its only exported function was used at just
one place and can be replaced by libc's realpath() (Arnaldo Carvalho de Melo)
- Use strerror_r() in the llvm infrastructure, tread safe, its what is used
elsewhere in tools/perf/ (Arnaldo Carvalho de Melo)
Cleanups:
- Removed misplaced or needless __maybe_unused/export (Arnaldo Carvalho de Melo)

Commit a674533078 ("tools lib traceevent: Split pevent_print_event()
into specific functionality functions") broke apart the function
pevent_print_event() into three functions.
The first function prints the comm, pid and CPU, the second prints the
timestamp.
But that commit added the printing of the CPU in the timestamp function,
which now causes pevent_print_event() to duplicate the CPU output.
Remove the redundant printing of the record's CPU from the timestamp
function.
