Merge tag 'perf-core-for-mingo' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/core
Pull perf/core improvements and fixes from Arnaldo Carvalho de Melo: User visible changes: - '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 kernel locks (hb->lock). (Davidlohr Bueso) Bug fixes: - Improve 'perf top' to survive 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 changes: - 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) Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com> Signed-off-by: Ingo Molnar <mingo@kernel.org>
