[PATCH v19 0/7] Control-flow Enforcement: Indirect Branch Tracking

[Yu-cheng Yu <yu-cheng.yu@intel.com>]

Control-flow Enforcement (CET) is a new Intel processor feature that blocks
return/jump-oriented programming attacks.  Details are in "Intel 64 and
IA-32 Architectures Software Developer's Manual" [1].

This is the second part of CET and enables Indirect Branch Tracking (IBT).
It is built on top of the shadow stack series.

This version has no changes from v18.  It is being re-sent as v19 to
synchronize with the shadow stack series v19.
