Merge tag 'perf-core-for-mingo-4.12-20170503' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/urgent
Pull perf/core improvements and fixes from Arnaldo Carvalho de Melo:
Fixes:
- Support setting probes in versioned user space symbols, such as
pthread_create@@GLIBC_2.1, picking the default one, more work
needed to make it possible to set it on the other versions, as
the 'perf probe' syntax already uses @ for other purposes.
(Paul Clarke)
- Do not special case address zero as an error for routines that
return addresses (symbol lookup), instead use the return as the
success/error indication and pass a pointer to return the address,
fixing 'perf test vmlinux' (the one that compares address between
vmlinux and kallsyms) on s/390, where the '_text' address is equal
to zero (Arnaldo Carvalho de Melo)
Infrastructure changes:
- More header sanitization, moving stuff out of util.h into
more appropriate headers and objects and sometimes creating
new ones (Arnaldo Carvalho de Melo)
- Refactor a duplicated code for obtaining config file name (Taeung Song)
