[PATCH 0/2] elf: Update GNU_PROPERTY_X86_XXX macros

[H.J. Lu]

This set of patches updates GNU_PROPERTY_X86_XXX macros according to the
x86 program property in x86-64 psABI:

https://github.com/hjl-tools/x86-psABI/wiki/x86-64-psABI-property.pdf

The NT_GNU_PROPERTY_TYPE_0 note is used to describe features and
capabilities supported by ELF binaries.  Consumers of ELF binaries can
consult the NT_GNU_PROPERTY_TYPE_0 note to make appropriate decisions.
If a consumer of ELF binaries ignores NT_GNU_PROPERTY_TYPE_0 note, nothing
is changed.  The new GNU_PROPERTY_X86_UINT32_VALID bit is used by
_dl_process_cet_property_note to detect if the NT_GNU_PROPERTY_TYPE_0
note is generated by updated linkers so that it can stop checking for
invalid .note.gnu.property section.

  elf: Update GNU_PROPERTY_X86_XXX macros [BZ #23797]
  x86/CET: Stop if the GNU_PROPERTY_X86_UINT32_VALID bit is set
