[PATCH 00/23] CET: Prepare for CET enabling

["H.J. Lu" <hjl dot tools at gmail dot com>]

This is the first set of patches to enable CET, excluding changes which
use the new CET system calls.  The complete set of patches is available
on hjl/cet/master branch at:

https://github.com/hjl-tools/glibc/tree/hjl/cet/master

I will submit the second set of patches with the new CET system calls,
which are on Linux kernel CET branch:

https://github.com/yyu168/linux_cet

later.
