Here, as promised, is version 10 of the stack-protected glibc patch,

Like the last, it's against glibc head as of Sat Nov 26, bf469f0ce98.
Tested with these flag combinations on {i686,x86_64)-pc-linux-gnu (with GCC
6.2.1-20161118, binutils 2.27.0.20160920, and kernel headers for v4.7.4):
Thanks for posting the updated series.
I tested this with build-many-glibcs.py, and ran into an ICE on tile*.
Filed as:

The good news is that ABI and PLT checking passes everywhere. Yay!
The explicit_bzero test case (string/tst-xbzero-opt.c) now fails. This
is probably test case bug, for which I will post a patch shortly.
I'll go through the updates series again, probably tomorrow.
Thanks,
Florian
