The last one isn't applying:

Applying: perf build: Fix python/perf.so library's name
error: patch failed: tools/perf/Makefile.perf:642
error: tools/perf/Makefile.perf: patch does not apply
Patch failed at 0005 perf build: Fix python/perf.so library's name
hint: Use 'git am --show-current-patch=diff' to see the failed patch
When you have resolved this problem, run "git am --continue".
If you prefer to skip this patch, run "git am --skip" instead.
To restore the original branch and stop patching, run "git am --abort".
⬢[acme@toolbox perf]$

I'll have the first 4 applied to make progress, later I'll check what
went wrong and to fix it.
