[PATCH v2] arm64/sve: ELF: Reserve ELF note number for SVE

[PATCH v2] arm64/sve: ELF: Reserve ELF note number for SVE

[Dave Martin]

Since the ELF note assignment that will be required for supporting
the Scalable Vector Extension is well understood, it makes sense to
reserve the relevant number now in order to help other projects
coordinate.

This patch documents reservation for the expcted assignment.

Later patches implementing SVE support will replace this
reservation with the appropriate #define.
