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 v16: - Rebase to v5.10-rc7. - Small changes to reflect Kconfig changes that replaces Shadow Stack and IBT options with just one option. - Update commit logs.
