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) Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com> Signed-off-by: Ingo Molnar <mingo@kernel.org>
