hi,
one of the patches is breaking test 4:

[jolsa@...va perf]$ sudo ./perf test
 1: vmlinux symtab matches kallsyms                        : Ok
 2: detect open syscall event                              : Ok
 3: detect open syscall event on all cpus                  : Ok
 4: read samples using the mmap interface                  :Can't parse sample, err = -14
 FAILED!

haven't checked deeply, but my guess is this one ;-)
