Merge tag 'perf-urgent-for-mingo' of git://git.kernel.org/pub/scm/linux/kernel/git...

Pull perf/urgent fixes from Arnaldo Carvalho de Melo:

 * Check for SIGINT in more loops, allowing tools such as 'perf report' to
   react faster to Ctrl+C, from Arnaldo Carvalho de Melo.

 * Fix objdump line parsing offset validation in the annotate code,
   from Adrian Hunter.

 * Fix buildid cache handling of kallsyms with kcore, from Adrian Hunter.

 * Fix compile with libelf without get_phdrnum, from Adrian Hunter.

 * Sharpen the libaudit dependencies test, refusing to build with older
   libraries that doesn't have all the functions used by 'perf trace", fix
   from Ingo Molnar.

 * Fill in new definitions for madvise()/mmap() flags to fix the build in
   older systems, from Ingo Molnar.

 * Fix old GCC build error in older systems in the kallsyms parsing code in
   trace-event-parse.c, from Ingo Molnar.

 * Ignore DWARF declaration tags, allowing, for instance, that the

     $ perf probe -L getname

   command succeeds in showing the source code for the 'getname' kernel
   function, telling in which lines probes can be inserted, fix from
   Masami Hiramatsu.

 * Fix linux/magic.h related build breakage in some systems, fix from
   Vinson Lee.
