Subject: [PATCH v17 0/7] Control-flow Enforcement: Indirect Branch Tracking

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.

Changes in v17:
- Rebase to v5.11-rc1.
