The previous version of CET Branch Tracking/PTRACE patches is at the following
link:

  https://lkml.org/lkml/2018/10/11/662

Summary of changes from v5:

  Remove the legacy code bitmap allocation from kernel.  Now GLIBC
  allocates the bitmap and passes it to the kernel.

  Some small fixes.

H.J. Lu (3):
  x86: Insert endbr32/endbr64 to vDSO
  x86/vsyscall/32: Add ENDBR32 to vsyscall entry point
  x86/vsyscall/64: Add ENDBR64 to vsyscall entry points

Yu-cheng Yu (8):
  x86/cet/ibt: Add Kconfig option for user-mode Indirect Branch Tracking
  x86/cet/ibt: User-mode indirect branch tracking support
  x86/cet/ibt: Add IBT legacy code bitmap setup function
  mm/mmap: Add IBT bitmap size to address space limit check
  x86/cet/ibt: ELF header parsing for IBT
  x86/cet/ibt: Add arch_prctl functions for IBT
  x86/cet/ibt: Add ENDBR to op-code-map
  x86/cet: Add PTRACE interface for CET
