The previous version of CET patches can be found in the following
link:

  https://lkml.org/lkml/2018/8/30/582

Summary of changes from v3:

  Move IBT legacy code bitmap allocation back to when the application
  requests it.  Most application do not need the bitmap.  It is only
  used when an application does dlopen() a legacy library.

  In the previous version, we pre-allocated the bitmap for every IBT-
  enabled application to avoid creating a hole in the linear address.
  However, this created a problem when the system has limited memory.
