Summary of changes in v2:

  Small fixes in the XSAVES patches.
  Improve: Documentation/x86/intel_cet.txt.

  Use shadow stack restore token for signals; save SHSTK pointer after FPU.
  Rewrite ELF header parsing.
  Backward compatibility is now handled from GLIBC tunables.
  Add a new patch to can_follow_write_pte/pmd, for SHSTK.
  Remove blocking of mremap/madvice/munmap.
  Add Makefile checking CET support of assembler/compiler.
