When you are posting a change that is largely verbatim file moves, and
especially if you aren't expecting people to apply the patch themselves
with 'patch' (because you supplied a git branch, or because you advise
people they'll have to use 'git apply'), using 'git diff --renames' makes
the diff a lot easier to review.

> 	* nptl/sysdeps/unix/sysv/linux/powerpc/Makefile: Moved ...
> 	* sysdeps/unix/sysv/linux/powerpc/nptl/Makefile: ... here.

Not helpful.  At the end of the day, there should not be a
sysdeps/unix/sysv/linux/powerpc/nptl/ subdirectory at all.  You need to
merge the nptl/.../Makefile contents into the existing
sysdeps/unix/sysv/linux/powerpc/Makefile instead.  Note that they
really should have an 'ifeq ($(subdir),nptl)' conditional that the
old Makefile was missing.

The rest looks fine off hand.


Thanks,
Roland
