Date
Hi Ingo,

Please consider pulling,

The following changes since commit cb307113746b4d184155d2c412e8069aeaa60d42:

perf_event: Don't allow vmalloc() backed perf on powerpc (2015-05-08 12:26:01 +0200)

perf build: Disable libdw DWARF unwind when built with NO_DWARF (2015-05-08 16:43:14 -0300)

----------------------------------------------------------------
perf/core improvements and fixes:

User visible:

- 'perf probe' improvements (Masami Hiramatsu)

- Support glob wildcards for function name
- Support $params special probe argument: Collect all function arguments
- Make --line checks validate C-style function name.
- Add --no-inlines option to avoid searching inline functions

- Introduce new 'perf bench futex' benchmark: 'wake-parallel', to
measure parallel waker threads generating contention for kerne
locks (hb->lock) (Davidlohr Bueso)

Bug fixes:

- 'perf top' survives much longer on high core count machines, more work
needed to refcount more data structures besides 'struct thread' and fix
more races (Arnaldo Carvalho de Melo)

Infrastructure:

- Move barrier.h mb/rmb/wmb API from tools/perf/ to kernel like tools/arch/
hierarchy (Arnaldo Carvalho de Melo)

- Borrow atomic.h from the kernel, initially the x86 implementations
with a fallback to gcc intrinsics for the other arches, all the kernel
like framework in place for doing arch specific implementations,
preferrably cloning what is in the kernel to the greater extent
possible (Arnaldo Carvalho de Melo)

- Protect the 'struct thread' lifetime with a reference counter,
and protect data structures that contains its instances with
a mutex (Arnaldo Carvalho de Melo

- Disable libdw DWARF unwind when built with NO_DWARF (Naveen N. Rao)
