This series introduces CET - indirect branch tracking

The major task of indirect branch tracking is for the compiler to
insert the ENDBR instructions at all valid branch targets.

The kernel provides:
	CPUID enumeration and feature setup;
	Legacy bitmap allocation;
	Some basic supporting routines.

In this patch, there are also a CET command-line utility and
PTRACE support.

H.J. Lu (2):
  x86: Insert endbr32/endbr64 to vDSO
  tools: Add cetcmd

Yu-cheng Yu (5):
  x86/cet: Add Kconfig option for user-mode Indirect Branch Tracking
  x86/cet: User-mode indirect branch tracking support
  mm/mmap: Add IBT bitmap size to address space limit check
  x86/cet: add arcp_prctl functions for indirect branch tracking
  x86/cet: Add PTRACE interface for CET
