Pull perf tools fixes from Arnaldo Carvalho de Melo:

 - Fix segfault in the powerpc specific arch_skip_callchain_idx
   function. The patch doing the reference count init/exit that went
   into 6.5 missed this function.

 - Fix regression reading the arm64 PMU cpu slots in sysfs, a patch
   removing some code duplication ended up duplicating the /sysfs prefix
   for these files.

 - Fix grouping of events related to topdown, addressing a regression on
   the CSV output produced by 'perf stat' noticed on the downstream tool
   toplev.

 - Fix the uprobe_from_different_cu 'perf test' entry, it is failing
   when gcc isn't available, so we need to check that and skip the test
   if it is not installed.
